Okay guys how do I uninstall a kernel ?

sudo dnf remove kernel-5.7.10-201.fc32.x86_64

does absolutely nothing.

I can even boot from the removed kernel after the removal.

How do I remove a kernel for good ?

I want it gone from the GRUB boot menu too.

I just upgraded to the new 5.7 kernel and it has a lot of bugs.

It can't even initialize my swap file:

This doesn't happen in 5.6

There are a slew of other problems.


A log file can be found here:

I really am too tired to file a bug since nothing really gets fixed.


What I want to do is uninstall the 5.7 kernel.

If I uninstall the kernel will running an older kernel cause problems during system upgrade ?
