Release 20.03 (“Markhor”, 2020.04/20)Highlights
In addition to numerous new and upgraded packages, this release has the
following highlights:
Support is planned until the end of October 2020, handing over to 20.09.
Core version changes:gcc: 8.3.0 -> 9.2.0glibc: 2.27 -> 2.30linux: 4.19 -> 5.4mesa: 19.1.5 -> 19.3.3openssl: 1.0.2u -> 1.1.1dDesktop version changes:plasma5: 5.16.5 -> 5.17.5kdeApplications: 19.08.2 -> 19.12.3gnome3: 3.32 -> 3.34pantheon: 5.0 -> 5.1.3
Linux kernel is updated to branch 5.4 by default (from 4.19).
Postgresql for NixOS service now defaults to v11.
The graphical installer image starts the graphical session automatically.
Before you'd be greeted by a tty and asked to enter systemctl start display-manager.
It is now possible to disable the display-manager from running by selecting the Disable display-manager
quirk in the boot menu.
GNOME 3 has been upgraded to 3.34. Please take a look at their
Release Notes
for details.
If you enable the Pantheon Desktop Manager via
, we now default to also use
Pantheon's newly designed greeter
.
Contrary to NixOS's usual update policy, Pantheon will receive updates during the cycle of
NixOS 20.03 when backwards compatible.
By default zfs pools will now be trimmed on a weekly basis.
Trimming is only done on supported devices (i.e. NVME or SSDs)
and should improve throughput and lifetime of these devices.
It is controlled by the services.zfs.trim.enable varname.
The zfs scrub service (services.zfs.autoScrub.enable)
and the zfs autosnapshot service (services.zfs.autoSnapshot.enable)
are now only enabled if zfs is set in config.boot.initrd.supportedFilesystems or
config.boot.supportedFilesystems. These lists will automatically contain
zfs as soon as any zfs mountpoint is configured in fileSystems.
nixos-option has been rewritten in C++, speeding it up, improving correctness,
and adding a option which prints all options and their values recursively.
and options were replaced by a single option to improve support for upstream session files. If you used something like:
services.xserver.desktopManager.default = "xfce";
services.xserver.windowManager.default = "icewm";
you should change it to:
services.xserver.displayManager.defaultSession = "xfce+icewm";
The testing driver implementation in NixOS is now in Python make-test-python.nix.
This was done by Jacek Galowicz (@tfc), and with the
collaboration of Julian Stecklina (@blitz) and
Jana Traue (@jtraue). All documentation has been updated to use this
testing driver, and a vast majority of the 286 tests in NixOS were ported to python driver. In 20.09 the Perl driver implementation,
make-test.nix, is slated for removal. This should give users of the NixOS integration framework
a transitory period to rewrite their tests to use the Python implementation. Users of the Perl driver will see
this warning everytime they use it:
$ warning: Perl VM tests are deprecated and will be removed for 20.09.
Please update your tests to use the python test driver.
See https://github.com/NixOS/nixpkgs/pull/71684 for details.
API compatibility is planned to be kept for at least the next release with the perl driver.
New Services
The following new services were added since the last release:
The kubernetes kube-proxy now supports a new hostname configuration
services.kubernetes.proxy.hostname which has to
be set if the hostname of the node should be non default.
UPower's configuration is now managed by NixOS and can be customized
via .
To use Geary you should enable instead of
just adding it to .
It was created so Geary could function properly outside of GNOME.

When upgrading from a previous release, please be aware of the following
incompatible changes:
The dhcpcd package
does not request IPv4 addresses for tap and bridge interfaces anymore by default.
In order to still get an address on a bridge interface, one has to disable
networking.useDHCP and explicitly enable
networking.interfaces.<name>.useDHCP on
every interface, that should get an address via DHCP. This way, dhcpcd
is configured in an explicit way about which interface to run on.
GnuPG is now built without support for a graphical passphrase entry
by default. Please enable the gpg-agent user service
via the NixOS option programs.gnupg.agent.enable.
Note that upstream recommends using gpg-agent and
will spawn a gpg-agent on the first invocation of
GnuPG anyway.
The dynamicHosts option has been removed from the
NetworkManager
module. Allowing (multiple) regular users to override host entries
affecting the whole system opens up a huge attack vector.
There seem to be very rare cases where this might be useful.
Consider setting system-wide host entries using
networking.hosts, provide
them via the DNS server in your network, or use
environment.etc
to add a file into /etc/NetworkManager/dnsmasq.d
reconfiguring hostsdir.
The 99-main.network file was removed. Matching all
network interfaces caused many breakages, see
#18962
and #71106.
We already don't support the global networking.useDHCP,
networking.defaultGateway and
networking.defaultGateway6 options
if networking.useNetworkd is enabled,
but direct users to configure the per-device
networking.interfaces.<name>.… options.
The stdenv now runs all bash with set -u, to catch the use of undefined variables.
Before, it itself used set -u but was careful to unset it so other packages' code ran as before.
Now, all bash code is held to the same high standard, and the rather complex stateful manipulation of the options can be discarded.
The SLIM Display Manager has been removed, as it has been unmaintained since 2013.
Consider migrating to a different display manager such as LightDM (current default in NixOS),
SDDM, GDM, or using the startx module which uses Xinitrc.
The Way Cooler wayland compositor has been removed, as the project has been officially canceled.
There are no more way-cooler attribute and programs.way-cooler options.
The BEAM package set has been deleted. You will only find there the different interpreters.
You should now use the different build tools coming with the languages with sandbox mode disabled.
There is now only one Xfce package-set and module. This means that attributes xfce4-14
and xfceUnstable all now point to the latest Xfce 4.14
packages. And in the future NixOS releases will be the latest released version of Xfce available at the
time of the release's development (if viable).
The phpfpm module now sets
PrivateTmp=true in its systemd units for better process isolation.
If you rely on /tmp being shared with other services, explicitly override this by
setting serviceConfig.PrivateTmp to false for each phpfpm unit.
KDE’s old multimedia framework Phonon no longer supports Qt 4. For that reason, Plasma desktop also does not have option any more.
The BeeGFS module has been removed.
The osquery module has been removed.
Going forward, ~/bin in the users home directory will no longer be in PATH by default.
If you depend on this you should set the option environment.homeBinInPath to true.
The aforementioned option was added this release.
The buildRustCrate infrastructure now produces lib outputs in addition to the out output.
This has led to drastically reduced closure sizes for some rust crates since development dependencies are now in the lib output.
Pango was upgraded to 1.44, which no longer uses freetype for font loading. This means that type1
and bitmap fonts are no longer supported in applications relying on Pango for font rendering
(notably, GTK application). See
upstream issue for more information.
The roundcube module has been hardened.
The password of the database is not written world readable in the store any more. If database.host is set to localhost, then a unix user of the same name as the database will be created and PostreSQL peer authentication will be used, removing the need for a password. Otherwise, a password is still needed and can be provided with the new option database.passwordFile, which should be set to the path of a file containing the password and readable by the user nginx only. The database.password option is insecure and deprecated. Usage of this option will print a warning.
A random des_key is set by default in the configuration of roundcube, instead of using the hardcoded and insecure default. To ensure a clean migration, all users will be logged out when you upgrade to this release.
The packages openobex and obexftp
are no longer installed when enabling Bluetooth via
.
The dump1090 derivation has been changed to use FlightAware's dump1090
as its upstream. However, this version does not have an internal webserver anymore. The
assets in the share/dump1090 directory of the derivation can be used
in conjunction with an external webserver to replace this functionality.
The fourStore and fourStoreEndpoint modules have been removed.
Polkit no longer has the user of uid 0 (root) as an admin identity.
We now follow the upstream default of only having every member of the wheel
group admin privileged. Before it was root and members of wheel.
The positive outcome of this is pkexec GUI popups or terminal prompts
will no longer require the user to choose between two essentially equivalent
choices (whether to perform the action as themselves with wheel permissions, or as the root user).
NixOS containers no longer build NixOS manual by default. This saves evaluation time,
especially if there are many declarative containers defined. Note that this is already done
when <nixos/modules/profiles/minimal.nix> module is included
in container config.
The kresd services deprecates the interfaces option
in favor of the listenPlain option which requires full
systemd.socket compatible
declaration which always include a port.
Virtual console options have been reorganized and can be found under
a single top-level attribute: console.
The full set of changes is as follows:
i18n.consoleFont renamed to
console.font
i18n.consoleKeyMap renamed to
console.keyMap
i18n.consoleColors renamed to
console.colors
i18n.consolePackages renamed to
console.packages
i18n.consoleUseXkbConfig renamed to
console.useXkbConfig
boot.earlyVconsoleSetup renamed to
console.earlySetup
boot.extraTTYs renamed to
console.extraTTYs
The awstats module has been rewritten
to serve stats via static html pages, updated on a timer, over nginx,
instead of dynamic cgi pages over apache.
Minor changes will be required to migrate existing configurations. Details of the
required changes can seen by looking through the awstats
module.
The httpd module no longer provides options to support serving web content without defining a virtual host. As a
result of this the services.httpd.logPerVirtualHost
option now defaults to true instead of false. Please update your
configuration to make use of services.httpd.virtualHosts.
The services.httpd.virtualHosts.<name>
option has changed type from a list of submodules to an attribute set of submodules, better matching
services.nginx.virtualHosts.<name>.
This change comes with the addition of the following options which mimic the functionality of their nginx counterparts:
services.httpd.virtualHosts.<name>.addSSL,
services.httpd.virtualHosts.<name>.forceSSL,
services.httpd.virtualHosts.<name>.onlySSL,
services.httpd.virtualHosts.<name>.enableACME,
services.httpd.virtualHosts.<name>.acmeRoot, and
services.httpd.virtualHosts.<name>.useACMEHost.
For NixOS configuration options, the loaOf type has
been deprecated and will be removed in a future release. In nixpkgs,
options of this type will be changed to attrsOf
instead. If you were using one of these in your configuration, you will
see a warning suggesting what changes will be required.
For example, users.users is a
loaOf option that is commonly used as follows:
users.users =
[ { name = "me";
description = "My personal user.";
isNormalUser = true;
}
];
This should be rewritten by removing the list and using the
value of name as the name of the attribute set:
users.users.me =
{ description = "My personal user.";
isNormalUser = true;
};
For more information on this change have look at these links:
issue #1800,
PR #63103.
For NixOS modules, the types types.submodule and types.submoduleWith now support
paths as allowed values, similar to how imports supports paths.
Because of this, if you have a module that defines an option of type
either (submodule ...) path, it will break since a path
is now treated as the first type instead of the second. To fix this, change
the type to either path (submodule ...).
The Buildkite
Agent module and corresponding packages have been updated to
3.x, and to support multiple instances of the agent running at the
same time. This means you will have to rename
services.buildkite-agent to
services.buildkite-agents.<name>. Furthermore,
the following options have been changed:
services.buildkite-agent.meta-data has been renamed to
services.buildkite-agents.<name>.tags,
to match upstreams naming for 3.x.
Its type has also changed - it now accepts an attrset of strings.
Theservices.buildkite-agent.openssh.publicKeyPath option
has been removed, as it's not necessary to deploy public keys to clone private
repositories.
services.buildkite-agent.openssh.privateKeyPath
has been renamed to
buildkite-agents.<name>.privateSshKeyPath,
as the whole openssh now only contained that single option.
services.buildkite-agents.<name>.shell
has been introduced, allowing to specify a custom shell to be used.
The citrix_workspace_19_3_0 package has been removed as
it will be EOLed within the lifespan of 20.03. For further information,
please refer to the support and maintenance information from upstream.
The gcc5 and gfortran5 packages have been removed.
The module has been removed.
It was only intended for use in internal NixOS tests, and gave the false impression
of it being a special display manager when it's actually LightDM.
Please use the options instead,
or any other display manager in NixOS as they all support auto-login. If you used this module specifically
because it permitted root auto-login you can override the lightdm-autologin pam module like:
security.pam.services.lightdm-autologin.text = lib.mkForce ''
auth requisite pam_nologin.so
auth required pam_succeed_if.so quiet
auth required pam_permit.so
account include lightdm
password include lightdm
session include lightdm
'';
The difference is the:
auth required pam_succeed_if.so quiet
line, where default it's:
auth required pam_succeed_if.so uid >= 1000 quiet
not permitting users with uid's below 1000 (like root).
All other display managers in NixOS are configured like this.
There have been lots of improvements to the Mailman module. As
a result,
The
option has been renamed to .
The
option has been removed. This is because having an option
for the Hyperkitty API key meant that the API key would be
stored in the world-readable Nix store, which was a
security vulnerability. A new Hyperkitty API key will be
generated the first time the new Hyperkitty service is run,
and it will then be persisted outside of the Nix store. To
continue using Hyperkitty, you must set to
true.
Additionally, some Postfix configuration must now be set
manually instead of automatically by the Mailman module:
= [ "hash:/var/lib/mailman/data/postfix_domains" ];
.transport_maps = [ "hash:/var/lib/mailman/data/postfix_lmtp" ];
.local_recipient_maps = [ "hash:/var/lib/mailman/data/postfix_lmtp" ];
This is because some users may want to include other values
in these lists as well, and this was not possible if they
were set automatically by the Mailman module. It would not
have been possible to just concatenate values from multiple
modules each setting the values they needed, because the
order of elements in the list is significant.
The LLVM versions 3.5, 3.9 and 4 (including the corresponding CLang versions) have been dropped.
The option has
been replaced by .
The new option allows better control of the IPv6 temporary addresses,
including completely disabling them for interfaces where they are not
needed.
Rspamd was updated to version 2.2. Read
the upstream migration notes carefully. Please be especially
aware that some modules were removed and the default Bayes backend is
now Redis.
The *psu versions of oraclejdk8 have been removed
as they aren't provided by upstream anymore.
The module has been removed
as it used the deprecated version of dnscrypt-proxy. We've added
to use the supported version.
This module supports configuration via the Nix attribute set
, or by passing a TOML configuration file via
.
# Example configuration:
services.dnscrypt-proxy2.enable = true;
services.dnscrypt-proxy2.settings = {
listen_addresses = [ "127.0.0.1:43" ];
sources.public-resolvers = {
urls = [ "https://download.dnscrypt.info/resolvers-list/v2/public-resolvers.md" ];
cache_file = "public-resolvers.md";
minisign_key = "RWQf6LRCGA9i53mlYecO4IzT51TGPpvWucNSCh1CBM0QTaLn73Y7GFO3";
refresh_delay = 72;
};
};
services.dnsmasq.enable = true;
services.dnsmasq.servers = [ "127.0.0.1#43" ];
qesteidutil has been deprecated in favor of qdigidoc.
sqldeveloper_18 has been removed as it's not maintained anymore,
sqldeveloper has been updated to version 19.4.
Please note that this means that this means that the oraclejdk is now
required. For further information please read the
release notes.
Haskell env and shellFor dev shell environments now organize dependencies the same way as regular builds.
In particular, rather than receiving all the different lists of dependencies mashed together as one big list, and then partitioning into Haskell and non-Hakell dependencies, they work from the original many different dependency parameters and don't need to algorithmically partition anything.
This means that if you incorrectly categorize a dependency, e.g. non-Haskell library dependency as a buildDepends or run-time Haskell dependency as a setupDepends, whereas things would have worked before they may not work now.
The gcc-snapshot-package has been removed. It's marked as broken for >2 years and used to point
to a fairly old snapshot from the gcc7-branch.
The nixos-build-vms8-script now uses the python test-driver.
The riot-web package now accepts configuration overrides as an attribute set instead of a string.
A formerly used JSON configuration can be converted to an attribute set with builtins.fromJSON.
The new default configuration also disables automatic guest account registration and analytics to improve privacy.
The previous behavior can be restored by setting config.riot-web.conf = { disable_guests = false; piwik = true; }.
Stand-alone usage of Upower now requires
instead of just installing into
.
nextcloud has been updated to v18.0.2. This means
that users from NixOS 19.09 can't upgrade directly since you can only move one version
forward and 19.09 uses v16.0.8.
To provide a safe upgrade-path and to circumvent similar issues in the future, the following
measures were taken:
The pkgs.nextcloud-attribute has been removed and replaced with
versioned attributes (currently pkgs.nextcloud17 and
pkgs.nextcloud18). With this change major-releases can be backported
without breaking stuff and to make upgrade-paths easier.
Existing setups will be detected using
system.stateVersion: by default,
nextcloud17 will be used, but will raise a warning which notes
that after that deploy it's recommended to update to the latest stable version
(nextcloud18) by declaring the newly introduced setting
services.nextcloud.package.
Users with an overlay (e.g. to use nextcloud at version
v18 on 19.09) will get an evaluation error
by default. This is done to ensure that our
package-option doesn't select an
older version by accident. It's recommended to use pkgs.nextcloud18
or to set package to
pkgs.nextcloud explicitly.
Please note that if you're coming from 19.03 or older, you have
to manually upgrade to 19.09 first to upgrade your server
to Nextcloud v16.
Hydra has gained a massive performance improvement due to
some database schema
changes by adding several IDs and better indexing. However, it's necessary
to upgrade Hydra in multiple steps:
At first, an older version of Hydra needs to be deployed which adds those
(nullable) columns. When having set stateVersion
to a value older than 20.03, this package will be selected
by default from the module when upgrading. Otherwise, the package can be deployed using
the following config:
{ pkgs, ... }: {
services.hydra.package = pkgs.hydra-migration;
}
Automatically fill the newly added ID columns on the server by running the following
command:
$ hydra-backfill-ids
Please note that this process can take a while depending on your database-size!
Deploy a newer version of Hydra to activate the DB optimizations. This can be done by
using hydra-unstable. This package already includes
flake-support and is
therefore compiled against pkgs.nixFlakes.
If your stateVersion is set to
20.03 or greater, hydra-unstable will be used
automatically! This will break your setup if you didn't run the migration.
Please note that Hydra is currently not available with nixStable
as this doesn't compile anymore.
pkgs.hydra has been removed to ensure a graceful database-migration
using the dedicated package-attributes. If you still have pkgs.hydra
defined in e.g. an overlay, an assertion error will be thrown. To circumvent this,
you need to set to pkgs.hydra
explicitly and make sure you know what you're doing!
The TokuDB storage engine will be disabled in mariadb 10.5. It is recommended to switch
to RocksDB. See also TokuDB.
Other Notable ChangesSD images are now compressed by default using bzip2.
The nginx web server previously started its master process as root
privileged, then ran worker processes as a less privileged identity user
(the nginx user).
This was changed to start all of nginx as a less privileged user (defined by
services.nginx.user and
services.nginx.group). As a consequence, all files that
are needed for nginx to run (included configuration fragments, SSL
certificates and keys, etc.) must now be readable by this less privileged
user/group.
To continue to use the old approach, you can configure:
services.nginx.appendConfig = let cfg = config.services.nginx; in ''user ${cfg.user} ${cfg.group};'';
systemd.services.nginx.serviceConfig.User = lib.mkForce "root";
OpenSSH has been upgraded from 7.9 to 8.1, improving security and adding features
but with potential incompatibilities. Consult the
release announcement for more information.
PRETTY_NAME in /etc/os-release
now uses the short rather than full version string.
The ACME module has switched from simp-le to lego
which allows us to support DNS-01 challenges and wildcard certificates. The following options have been added:
security.acme.acceptTerms,
security.acme.certs.<name>.dnsProvider,
security.acme.certs.<name>.credentialsFile,
security.acme.certs.<name>.dnsPropagationCheck.
As well as this, the options security.acme.acceptTerms and either
security.acme.email or security.acme.certs.<name>.email
must be set in order to use the ACME module.
Certificates will be regenerated on activation, no account or certificate will be migrated from simp-le.
In particular private keys will not be preserved. However, the credentials for simp-le are preserved and
thus it is possible to roll back to previous versions without breaking certificate generation.
Note also that in contrary to simp-le a new private key is recreated at each renewal by default, which can
have consequences if you embed your public key in apps.
It is now possible to unlock LUKS-Encrypted file systems using a FIDO2 token
via .
Predictably named network interfaces get renamed in stage-1. This means that it is possible
to use the proper interface name for e.g. Dropbear setups.
For further reference, please read #68953 or the corresponding discourse thread.
The matrix-synapse-package has been updated to
v1.11.1.
Due to stricter requirements
for database configuration when using postgresql, the automated database setup
of the module has been removed to avoid any further edge-cases.
matrix-synapse expects postgresql-databases to have the options
LC_COLLATE and LC_CTYPE set to
'C' which basically
instructs postgresql to ignore any locale-based preferences.
Depending on your setup, you need to incorporate one of the following changes in your setup to
upgrade to 20.03:
If you use sqlite3 you don't need to do anything.If you use postgresql on a different server, you don't need
to change anything as well since this module was never designed to configure remote databases.
If you use postgresql and configured your synapse initially on
19.09 or older, you simply need to enable postgresql-support
explicitly:
{ ... }: {
services.matrix-synapse = {
enable = true;
/* and all the other config you've defined here */
};
services.postgresql.enable = true;
}If you deploy a fresh matrix-synapse, you need to configure
the database yourself (e.g. by using the
services.postgresql.initialScript
option). An example for this can be found in the
documentation of the Matrix module.
If you initially deployed your matrix-synapse on
nixos-unstableafter the 19.09-release,
your database is misconfigured due to a regression in NixOS. For now, matrix-synapse will
startup with a warning, but it's recommended to reconfigure the database to set the values
LC_COLLATE and LC_CTYPE to
'C'.
The systemd.network.links option is now respected
even when systemd-networkd is disabled.
This mirrors the behaviour of systemd - It's udev that parses .link files,
not systemd-networkd.
mongodb has been updated to version 3.4.24.
Please note that mongodb has been relicensed under their own
sspl-license. Since it's not entirely free and not OSI-approved,
it's listed as non-free. This means that Hydra doesn't provide prebuilt
mongodb-packages and needs to be built locally.
