Old kernels accumulate

Ask Fedora

Hello.

Every time Fedora is updated, old kernels accumulate.
Is there a good way to automatically remove old kernels that are no longer needed?

There should be a limit, that is 3 versions by default.

Maybe this topic could be useful: https://discussion.fedoraproject.org/t/pin-or-retain-a-kernel-version-or-increase-the-number-of-kernels-retained/72318/2

If you have more than 3 kernels installed for some reason, please tell us, we’ll troubleshoot it.

3 kernels is a good number to have, because sometimes after you boot new kernel you can have something not working or not working quite right) In such a case you can just reboot into older kernel that worked or. Some people ever recommend to increase the number of kernel Fedora has installed to five. I’m ok with three.

Thank you. Hope I can keep updating the kernel now until the day developers fixed the bug concerning amd graphics and I hope I can keep these two latest working kernel versions until the problem is really solved.

It didn’work. Last kernel update removed a locked kernel.

I set my boot partition too small and didn’t realize there was a limit. Resetting the partition to a larger size solved the problem.

Thank you.
