Hi, i’m trying to install kernel debuginfo to build a volatility profile, the problem is the version of the kernel with debug symbol is

kernel-debuginfo-5.17.5-300.fc36.x86_64

but i’am running on 6.3.4-201.fc38.x86_64, there is any chance that the packet have been renamed or someone will give me a workaround

Debuginfo packages are in separate repos, see dnf repolist --all *debuginfo. You should probably make sure you don’t have any F36 repos still enabled.

Easy way

Use debuginfo-install from dnf-plugins-core:

sudo dnf debuginfo-install kernel

Manual way

Enable repo(s) for one command only:

sudo dnf --enablerepo=fedora-debuginfo,updates-debuginfo install kernel-debuginfo

Enable repo(s) permanently (probably not what you want):

sudo dnf config-manager --set-enabled fedora-debuginfo updates-debuginfo

Disable repo(s):

sudo dnf config-manager --set-disabled fedora-debuginfo updates-debuginfo

Oh, I missed that you were on an outdated kernel. You need to upgrade first. Current kernel in F38 is 6.3.8-200.fc38.x86_64
