How do I remove/uninstall debug kernels?
Hi All,
At some point my system/kernel upgrades began installing debug kernels. I don't know what I installed/activated to cause this to happen, so I don't know how to disable/remove it. Can anyone please provide some guidance?
Thanks, mitch

Hi Mitch,
Check which kernel packages are installed : sudo dnf list installed | grep kernel
Remove the packages you want ro remove with sudo dnf remove <package-name>.
Below you see an example for removing kernel-devel from a RHEL 9.2 system. :)
sudo dnf list installed | grep kernel
