COPR custom kernel install not showing up in GRUB

marvinka · January 19, 2021, 3:47pm

Hey folks,

I’m new to messing with custom kernels and I’m trying to install gloriouseggrolls fsync enabled kernel from the copr. After enabling the repo, I followed the instructions in the description by appending exclude=kernel* to /etc/yum.repos.d/fedora-updates.repo, doing a sudo dnf update --refresh followed by sudo dnf distro-sync.

According to the dnf logs it did install and downgrade to the new kernel, but upon rebooting I don’t have the option to boot from the newly installed kernel in grub. I ran sudo grub2-mkconfig but that didn’t help either. The new kernel is also not in /boot.

I did a sudo find / -iname '*5.9.11-fsync*' as well and I think I found it in /usr/src/kernels/5.9.11-fsync.301.fc33.x86_64, although I’m not entirely sure what I’m looking at when it comes to kernels, or if it’s just the headers that live there. Seems to be the only place where the find command succeeded at least.

My search-engine skills don’t seem up to par for this, so here we are! Any idea what to do to get the new kernel to show up in grub? Let me know if you need more logs, I’m not really sure where I could find other relevant log entries to debug this.

Thans in advance!

Upon further inspection only kernel-headers and kernel-devel installed, but the main kernel package is for some reason not in that repo, or at least dnf doesn’t see it if I list packages. Wonder if it’s just a buggy copr repo rather than a problem on my end. There’s a whole bunch of installable packages at least, but I’m not sure how to tell dnf to fetch them from the copr repo. Here’s the available packages I get from the repo from dnf list

Solved it. Kind of. The description in the COPR could be more verbose though. Strangely, neither sudo dnf repo-pkgs copr:copr.fedorainfracloud.org:gloriouseggroll:kernel list all nor sudo dnf list --repo copr:copr.fedorainfracloud.org:gloriouseggroll:kernel nor sudo dnf list kernel nor sudo dnf list kernel-core or any other components showed the kernel from the copr, nor did it install by simple means such as sudo dnf install kernel, but by chance I started typing sudo dnf install kernel and tabbed a couple times and voila, the respective kernel packages showed up in the autocomplete suggestions.

If anyone knows how to make them show up via dnf search or dnf list as well, I’d be more than happy to hear it for future reference. Anyway, using the autocomplete suggestions I installed the necessary kernel packages via sudo dnf install kernel-5.9.11-fsync.301.fc33.x86_64 kernel-core-5.9.11-fsync.301.fc33.x86_64 kernel-modules-5.9.11-fsync.301.fc33.x86_64 kernel-modules-extra-5.9.11-fsync.301.fc33.x86_64 and am now happily on 5.9.11-fsync.301.fc33.x86_64.

So if anyone in the future comes across this with their favorite search engine, there you go. Maybe someone who actually knows more than very basic dnf usage can shed more light on why the packages didn’t show with e.g. dnf list kernel or dnf search.

I don’t use this copr repo, but I think /usr/src usually means source code, so you are expected to compile your own kernel. (Or maybe the copr repo owner put a precomplied kernel somewhere?)
You can use rpm -ql <package> to find what file <package>has installed. With fedora distribution kernel:

$ rpm -ql kernel-core-5.10.7
/boot/.vmlinuz-5.10.7-200.fc33.x86_64.hmac
/boot/System.map-5.10.7-200.fc33.x86_64
/boot/config-5.10.7-200.fc33.x86_64
/boot/initramfs-5.10.7-200.fc33.x86_64.img
/boot/symvers-5.10.7-200.fc33.x86_64.gz
/boot/vmlinuz-5.10.7-200.fc33.x86_64
/lib/modules
...
