Fedora/CentOS error: wireguard-dkms-1:0.0.20180420-1.fc28.noarch: erase failed

Fedora/CentOS error: wireguard-dkms-1:0.0.20180420-1.fc28.noarch: erase failed

[Joe Doss]

One of my coworkers stumbled on this error this morning where the 
WireGuard DKMS module would get removed by a kernel update and leave the 
wireguard-dkms-0.0.20180420-1.fc28.noarch RPM hanging out where it 
couldn't uninstall correctly. You will see this error on a dnf/yum update:

Failed:
   wireguard-dkms.noarch 1:0.0.20180513-1.fc28

You can verify the issue with this command:

# rpm -qa |grep wireguard-dkms
wireguard-dkms-0.0.20180513-1.fc28.noarch
wireguard-dkms-0.0.20180420-1.fc28.noarch

You will see the old snapshot RPM won't manually be removed like this:

# rpm -e wireguard-dkms-0.0.20180420-1.fc28.noarch
error: %preun(wireguard-dkms-1:0.0.20180420-1.fc28.noarch) scriptlet 
failed, exit status 3
error: wireguard-dkms-1:0.0.20180420-1.fc28.noarch: erase failed

You can fix this easily with:

# dkms install -m wireguard -v 0.0.20180420

Verify it is installed:

# dkms status
wireguard, 0.0.20180420, 4.16.6-302.fc28.x86_64, x86_64: installed 
(WARNING! Diff between built and installed module!)
wireguard, 0.0.20180513, 4.16.6-302.fc28.x86_64, x86_64: built
wireguard, 0.0.20180513, 4.16.7-300.fc28.x86_64, x86_64: installed

Manually remove the old snapshot RPM:

# rpm -e wireguard-dkms-0.0.20180420-1.fc28.noarch

Verify that it is uninstalled:

# rpm -qa |grep wireguard-dkms
wireguard-dkms-0.0.20180513-1.fc28.noarch

This issue seems to be a pretty rare edge case, and the fix is easy. I 
will try and improve the RPM so this can't happen in the future. Any 
ideas from the list on how to prevent this edge case are welcome.

Joe

[Germano Massullo]

I had the same problem, and I followed your guide till

> # rpm -e wireguard-dkms-0.0.20180420-1.fc28.noarch

Then I wanted to use 0.0.20180513-1.fc28 snapshot, so I runned

# dkms autoinstall

but I got errors

Error! Could not locate dkms.conf file.
File: /var/lib/dkms/wireguard/0.0.20180218/source/dkms.conf does not exis=

You should ask for suggestions in Fedora devel mailing list

I never use dkms autoinstall but I just used it and I cannot reproduce 
the problem. It looks based on /var/lib/dkms/wireguard/0.0.20180218/ it 
is looking for a snapshot from Feb. It could be that you are having 
different problems here. Maybe your system had issues back in Feb where 
it thought it removed the RPM but didn't?

Since I don't see the 0.0.20180218 RPM installed you most likely can 
manually remove /var/lib/dkms/wireguard/0.0.20180218/ and this error 
should go away.

It worked, thank you!
