  • This is located in /var/lib/dkms.

If an error is seen

dkms status

File: /var/lib/dkms/amdgpu/5.18.13-1577590.22.04/source/dkms.conf does not exist.

NOTE: dkms relies upon the source/dmks.conf file.

  • If this file is not found then dkms reports an error.

Find the offending module

for i in /var/lib/dkms/*/[^k]*/source; do [ -e "$i" ] || echo "$i";done

returns: 

/var/lib/dkms/amdgpu/5.18.13-1577590.22.04/source/

NOTE: This confirms the offending module.

To fix the dkms error

Go to the /var/lib/dkms directory for the specific module reporting the error. 

cd /var/lib/dkms/amdgpu

NOTE: In this example, the amdgpu module having the issue

Check what is installed in that directory

ls -al /var/lib/dkms/amdgpu/

returns: 

total 8.0K
drwxr-xr-x 3 root root 4.0K Jun  2 15:19 5.18.13-1577590.22.04/
drwxr-xr-x 3 root root 4.0K Jun 16 02:06 5.18.13-1580598.22.04/
lrwxrwxrwx 1 root root   46 Jun 16 02:06 kernel-5.19.0-45-generic-x86_64 -> 5.18.13-1580598.22.04/5.19.0-45-generic/x86_64/

NOTE: This shows 2 directories; and a link.

  • with the top one being reported as causing the error, when dkms status command is run.
  • The link and the associated directory it points to, are okay!

Remove the offending directory

sudo mv 5.18.13-1577590.22.04/ /home/peter/dkms_amd/

NOTE: For safety, the directory is just moved away to a backup directory, just in case it might be needed to be restored back.

WARNING: Do not remove the directory that is associated with the link, or all the sub-directories!

  • This WILL result in Ubuntu not being able to boot properly!

Check again what is installed in that directory

ls -al /var/lib/dkms/amdgpu/

returns: 

total 8.0K
drwxr-xr-x 3 root root 4.0K Jun 16 02:06 5.18.13-1580598.22.04/
lrwxrwxrwx 1 root root   46 Jun 16 02:06 kernel-5.19.0-45-generic-x86_64 -> 5.18.13-1580598.22.04/5.19.0-45-generic/x86_64/

NOTE: This shows only 1 directory.

  • with the link also pointing to this directory too.

Check that the module source does exist

The source of the actual module is found in /usr/src.

The link, in /var/lib/dkms/amdgpu should be pointing to the actual source. 

ls /usr/src/amdgpu-5.18.13-1580598.22.04/

returns: 

amd  dkms.conf  drm_gem_ttm_helper.c  firmware  include  Makefile  scheduler  ttm

NOTE: Good!

  • This shows that the dkms link does point to actual source.

Rebuild dkms modules

Rebuild all modules for the currently running kernel: 

dkms autoinstall

NOTE: If this does not return errors then it has worked!

Retry to check dkms status

To see if the above changes have corrected the error. 

dkms status

returns: 

amdgpu/5.18.13-1580598.22.04, 5.19.0-45-generic, x86_64: installed

NOTE: This shows there is a amdgpu dkms module.

  • The error has been corrected.
