Why does reinstalling a kernel remove my dkms modules?

Ask Fedora

Whenever I reinstall a kernel, all my dkms modules are deleted.

It seems like that shouldn’t happen so I am assuming I am missing a step?

Running scriptlet: kernel-core-5.6.19-300.fc32.x86_64                                                                               10/10

So…this just started working. Now when I re-install kernel-core it re-installs the dkms modules afterwards.

Unfortunately, I am not sure what changed so I think I may need to start from scratch and rebuild to see if that issues recurs. :face_with_monocle:
