In Ubuntu, I have put the few kernels that work flawlessly ON HOLD (locks it to prevent updater from removing them) by using these commands: First, I use “dpkg --list | grep linux-image” as this will show a list of installed kernel packages, such as linux-image-6.8.0-85-generic… Then I pick the ke…

I put installonly_limit=0 in my /etc/dnf/dnf.conf to make sure the ‘good’ kernels are ON HOLD so to speak and never get ‘lost’, and will just dump the ones that I have issues with… my /boot is 2Gb w/1.5Gb free, so plenty of room for now - will keep watch on it. Currently my Ubuntu grub’s Fedora pa…

Not possible in Fedora. It isn’t straightforward. If you still want to get new kernels and keep some you’ll have to do manual kernel removal like sudo dnf remove kernel*6.12.77* kernel*6.19.9* from time to time and prevent dnf from auto removing then by putting in your /etc/dnf/dnf.conf installonl…

There is the dnf versionlock plugin that should do the trick, although I’ve not used it with the kernel package: DNF versionlock Plugin — dnf-plugins-core 4.4.2-1 documentation

OK - so thankfully I’m using Ubuntu grub and not the Fedora grub - with that I can use Ubuntu’s Grub Customizer to tweak my bootloader. I can add newer Fedora kernels as they come along, test them, and reject them by removing the newest as default… Case in point: Currently my grub’s Fedora part of …

[image] Jaimie Blackstone: Updates, either Ubuntu or Fedora, are great at just breaking things under the guise of ‘fixing bugs’. I read you. Granted, they’re not tested a lot. Debian is way better at this for extra stability. I ran it since debian 2. I ran ubuntu once, years ago and it c…

I was aware of versionlock however a recent discussion mentioned it doesn’t work with kernels so I didn’t suggest it. I never tested it myself though.
