There might be incompatible modules that won't compile for the new kernel which results in a kernel header package installation failure. That's bad and not really correct, the incompatible DKMS module is the problem and not the new kernel. In this case, DKMS module build failures should be ignored so that the kernel installation completes. This is especially acute during release-upgrades, as dkms modules are upgraded out of order, and major kernel version are upgraded out of order. Majority of the time there is a new dkms available, which should attempt build & load. However, many modules are often remain broken, no longer needed, or need user to fetch updated versions themselves. [ Test Plan ] * Install jammy * Add module that support v5.15 kernel, but fails to compile with any newer kernels (one can find examples of such dkms modules in the archive, or out of the archive) * Perform release upgrade with patched dkms pre-installed * Release upgrade should succeed, despite unable to compile all dkms modules [ Where problems could occur ] * This is an improvement to the current situation of aborting release upgrade half way through. It doesn't quite resolve the UX to notify the user which dkms modules did not manage to compile, or to ask user to uninstall or to update them. Further UX / hooks might be needed in the release upgrade to complete the story of asking the user what they want to do with regressed dkms modules. [ Other Info ] * See lots and lots of upgrade bugs, failing on dkms module installation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dkms/+bug/2028366/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
