Fedora Linux 42 was released today[1]. The Fedora CoreOS testing stream has been rebased and is currently rolling out. This update will come to the stable stream in a few weeks.
For more information about Fedora 42, see the Fedora Project’s list of official Changes[2] and the Fedora CoreOS analysis of each Change[3].
There were a lot of changes on the Fedora CoreOS side going into this release that may require attention:
- In Fedora 42, all newly provisioned nodes will now be pulling updates from the OCI registry at Quay [4]. In the coming months existing nodes will be migrated as well using a migration script[5]. This has the potential to cause disruption in environments where proxies or firewalls need to be updated for this change.
- In Fedora 42, CoreOS has changed the backend for almost all disk image building to use OSBuild[6][7]. We don’t expect any meaningful changes to user experience as a result of this.
- In Fedora 42, the CoreOS Live ISO/PXE artifacts were changed to use EROFS as a backing filesystem[8].
- In Fedora 42, the
pam-ssh-agentRPM has been dropped[9]. If you layered this package previously it will need to be removed before systems can be updated.
Please test out the testing stream and report any issues in our issue tracker[10]!
