From Fedora Project Wiki

The updates-testing repository, also referred to as Test Updates, contains updates scheduled to be released for Branched pre-releases (after the Bodhi enabling point) and stable releases of Fedora. The updates-testing-modular repository is the equivalent repository for module updates. User testing and feedback provided via Bodhi, on the test mailing list and the relevant Bugzilla is vital to ensure that good updates are released quickly and bad ones kept away from release.

Using the updates-testing repositories

Enabling the repositories permanently

With dnf (Fedora 22 and later):

dnf config-manager --set-enabled updates-testing
dnf config-manager --set-enabled updates-testing-modular

Use dnf repolist to verify. To disable the repositories again, with dnf (Fedora 22 and later):

dnf config-manager --set-disabled updates-testing
dnf config-manager --set-disabled updates-testing-modular
dnf distro-sync will sync the packages to the versions available in the repository and might be useful to run after you disable the testing repository to downgrade packages back to the stable versions.

Note that the dnf config-manager command is available as part of the dnf-plugins-core package and should be installed by default on Fedora 22 and later.

Enabling the repositories temporarily

If you'd rather not enable the updates-testing repositories permanently but just use them on a case-by-case basis, you can do this with dnf. On Fedora 22 or later, use the command:

dnf update --enablerepo=updates-testing,updates-testing-modular

will update the entire system using packages from the updates-testing repositories, while the command:

dnf install <foo> --enablerepo=updates-testing,updates-testing-modular --best

will install or update only the package named <foo> from the updates-testing repositories.

Testing updates for EPEL with CentOS or RHEL

CentOS and RHEL (Until version 8) used yum instead of DNF, but the basic procedure for installing a particular test update for EPEL is similar:

yum install <foo> --enablerepo=epel-testing

will install or update only the package named <foo> from the epel-testing repository.

Using it with Fedora Silverblue (Kinoite, Sericea...)

rpm-ostree rebase fedora/32/x86_64/testing/silverblue

Going back to stable:

rpm-ostree rebase fedora/32/x86_64/silverblue

This affects the core Silverblue image itself. For testing updates to Flatpaks, see below. For other immutable variants, change 'silverblue' to 'kinoite', 'sericea' etc.

Testing updates for Fedora Flatpaks

To enable the testing remote:

flatpak remote-modify --enable fedora-testing

To switch to the build of a specific Flatpak from the fedora-testing remote:

flatpak install fedora-testing <> --reinstall

Replace <> with the correct name.

Using it with Fedora CoreOS

Fedora CoreOS offers a few update streams, but none of those directly follow the Fedora Bodhi Updates/Updates Testing repositories. Please follow the testing stream in Fedora CoreOS to preview what is coming to the next stable stream release.

What to test, testing, and reporting results

The Bodhi system is used to track and collate feedback on testing updates. All testing updates will be shown in the Bodhi system. The update feedback guidelines explain what feedback you should leave in what situations, based on your testing of the package.

In the web interface, each Works for me adds 1 to the test update's karma, while each Does not work subtracts 1 from it. Untested leaves the karma unchanged. Other tools present this in different ways, but the +1/-1/0 mechanism is the same.

By default, test updates with karma of 3 are automatically sent out as full official updates, while test updates with karma of -3 are automatically withdrawn from the testing repository. The Updates Policy specifies minimum levels of karma that different types of update must meet at different points in the development cycle. As you can see, your testing and feedback is vital to make sure that good updates are released quickly and bad ones don't get out to the general public.

For pre-releases, karma may be required for important package builds to become a part of the final release. Look out for mails to the test-announce mailing list requesting karma for specific builds.

Using fedora-easy-karma/fedora-update-feedback

There are tools you can use to ease the process of reporting your feedback.

fedora-easy-karma is available as a package for all supported Fedora releases. Installation instructions can be found here.

After installation, you can launch the tool at any time by running fedora-easy-karma in a console. If your FAS account name is not the same as your user name, use the --fas-username FAS_USERNAME parameter to specify your FAS account name. It will automatically discover what packages, if any, you currently have installed from the updates-testing repository (it currently supports only package updates, not module updates or flatpak updates), and let you file your feedback before moving on to the next package, all in one linear process.

fedora-update-feedback is another tool inspired by fedora-easy-karma that also allows submitting feedback for bugs and test cases in addition to providing a comment and karma. Instructions on configuring the tool can be found here.

Using the web interface

You can also give your feedback on a test update by using the Bodhi web interface. There is a Login link in the left-hand sidebar. Log in using your Fedora account. If you don't have a Fedora account, you can create an account here. Once you are logged in, you will be able to leave a comment on the update. To the right of the comment box are three radio button options that effect karma, represented by three icons that depict FAIL, Untested and PASS. The label for these options asks "Is the update generally functional?"

The icon on the left (which looks like an X) represents "FAIL - Does not fix the bug or pass the test case." The middle option (shaped like an open box) indicates "Untested". And the rightmost icon (which looks like a check mark) designates "PASS - Fixes the bug or passes the test case." These options will leave -1, 0, or +1 karma respectively for the update.

Updates-testing enabled by default in development (Branched) releases

In Fedora Branched releases - the next release, once it has branched from Rawhide, but before it is released - the updates-testing repositories are enabled by default. Package maintainers in Fedora are encouraged to test their updates via these repositories first to keep the development branch more robust while providing the latest updates. If you are a tester, it is recommended to leave these repositories enabled and provide feedback to help make the general release that follows a robust one. In the development branch, packages that are in the updates-testing repositories will move into the relevant base repository when approved, not the relevant updates repository.

Before release, a fedora-release update will automatically disable the updates-testing repositories and enable the updates repositories. After the general release, the updates repositories will start filling up as more updates gets pushed through but until the release time, updates repositories will remain empty.
