Not Stable yet.

The update is still in testing, not pushed to stable yet (like @scald said).

If you want to install it before it’s approved for stable, then the Bodhi page that I linked to above shows the dnf command to do so.

I read a post on Fedora subreddit, the OP said is using 6.18.

Excuse me.

Right - they could be using Rawhide, or they could have used the testing repos to install the update on Fedora 42 / 43 before official stable release.

It is in the testing repo I have been using it for several days.

Fedora pushed the 6.18 to stable for Fedora 42 then they found regressions and held off pushing it to Fedora 43.

Do you know what the Bodhi update for that was?

This one is 6.18.3 for Fedora 42, but the history there suggests that it has never been pushed to stable.

Been a while but seems like it has been deleted from reddit where someone posted they have Fedora 42 with 6.18 stable on their system wondering why 42 has it but 43 don’t, links to the repo site too showing 42 as stable and 43 as testing for the 6.18 kernel.

The 6.18.3 kernel is in the updates-testing repo for both f42 & f43 (and has been for several days) if you wish to install it. I have done so on f43 and have had no issues with it.

sudo dnf upgrade kernel\* --enablerepo updates-testing

I installed 6.18.3 on several systems aged 12 to 0 years (newest being aarch64 in a VM) but have only done basic tests. So far no issues.

6.18.3 is now in the stable repos for Fedora 42 and Fedora 43.

hi new here. upgrading from 6.17 to 6.18 results in no wifi no gpu drivers and probably other things. is there a way to clear the 6.18 image so I can try reapplying the updates?

i think the issues started while trying to update with no hdd space. also tried to run “sudo dnf upgrade” after clearing some space, but same issue after reboot.

This topic has guidance on how to work around space issues during kernel updates:

Particularly, you can remove a particular kernel version with:

sudo dnf remove "kernel*-6.17.3-301*"

(replace the kernel version there with the one you want to remove)

thanks for the reply. now how do I find the kernels installed? Updates normally work so I don’t know how to find all the information.

16

dnf list --installed "kernel*" should show you this.

17

thanks for the superquick replys . do I need to do anything to grub before trying to reboot and reapplying the updates?

18

You shouldn’t need to do anything manually. Removing the packages using dnf will clean up the state of GRUB (specifically, by removing the entries in the /boot/loader/entries directory).

19

yay , I have all the updates but running on the old kernel. NICE =) I think I’ll just wait for the next kernel update. thank you so much =)
