Fedora DKMS Issues

[Joe Doss]

Hi All,

We have been seeing some issues where DKMS is no longer upgrading 
cleanly on Fedora. This is due to the older version's DKMS conf file 
getting remove prematurely and you end up with this error `Error! Could 
not locate dkms.conf file.` when running any dkms commands.

I have a working RPM that does not cause this error with my testing on 
Fedora 29 and CentOS 7, so I have pushed it up to Copr 
(https://copr.fedoraproject.org/coprs/jdoss/wireguard/build/854203/). I 
_think_ this should fix things moving forward, but this issue has been 
hard to reproduce, so I am starting this thread to gather feedback if it 
doesn't fix the problem.

Please upgrade to wireguard-dkms-0.0.20190123-2 to give this a try. Once 
Jason releases the next snapshot, we can see if users running this 
version break on the upgrade or not. Please note that this new RPM won't 
fix your WireGuard DKMS install if it is already in a broken state. You 
will need to totally remove the older wireguard-dkms RPM and install 
this new one.

The gist of the underlying issue is this is a DKMS problem that is not 
very well documented. 
https://github.com/dell/dkms/issues/25#issuecomment-360275619 is the GH 
Issue that I followed when trying to track this problem down. Using 
%posttrans vs %post in the RPM feels hacky and not the best solution, 
but it should do for now. From what I can tell ZFS on Linux DKMS RPM had 
similar problems and they solved with with some bash 
(https://github.com/zfsonlinux/zfs/pull/8216). I am hoping this abuse of 
%posttrans limps us along until Linux 5.0.

Please leave feedback on this new version in this thread.

Thanks,
Joe
