If you are using the latest ZFS the drivers are built into the kernel so the zfs-dkms package should be removed.

Status changed to 'Confirmed' because the bug affects multiple users.

[Colin Ian King (colin-king)]

Hi, can you attach to the bug report the output from the following command:

sudo apt list --installed

[elevenfive (elevenfive)]

$ sudo apt list --installed | grep -i zfs

Can I have the complete list please as I'm trying to figure out if there are missing packages that are the root issue.

[elevenfive (elevenfive)]

Hi Sorry I'm not comfortable sharing all my installed packages. I haven't seen this issue since upgrading to 20-04 btw.

[Colin Ian King (colin-king)]

OK. I fully understand your concerns with sharing that information. Normally this issue occurs if you have the zfs-dkms modules installed - these are no longer required so you can safely remove zfs-dkms if you haven't done so already. I was suspecting that some dkms dependency (such as a tool chain or specific kernel headers were missing or some gcc issue) was causing this issue.

[Colin Ian King (colin-king)]

Given it's probably not going to happen to you again (since it was an upgrade glitch), are you OK if we close this bug?

[Colin Ian King (colin-king)]

No response for a while. Closing as Won't Fix.
