Ubuntu – dkms does not automatically rebuild after kernel upgrade

16.04dkmskernelupgrade

as mentioned in the title all DKMS modules installed on my system won't be automatically rebuilt after a kernel upgrade.

# ls -la /var/lib/dkms/
total 32K
drwxr-xr-x  7 root root 4.0K May 26 11:55 .
drwxr-xr-x 86 root root 4.0K May 25 19:33 ..
drwxr-xr-x  4 root root 4.0K May 25 18:56 anbox-modules-ashmem
drwxr-xr-x  4 root root 4.0K May 25 18:57 anbox-modules-binder
drwxr-xr-x  3 root root 4.0K May  2 18:34 bbswitch

drwxr-xr-x  3 root root 4.0K May 26 11:55 nvidia-381
drwxr-xr-x  3 root root 4.0K May 26 11:55 virtualbox

I always have to rebuild it manually after a kernel upgrade.
If there are any logs or configs needed to diagnose this problem I will supply them as soon as possible.

From the comments...

There were multiple problems to solve.

  • we removed the /usr/src/gmock and /usr/src/gtest as they weren't dkms software modules. If you need this software for some reason, either reinstall it, or create ~/src and put the gmock/gtest software there, and do the appropriate make commands (or whatever) to build that software.

  • we removed the /var/lib/dkms/anbox* directories as they were missing their associated /usr/src/anbox* source code due to an incomplete uninstall, and caused the dkms status command to fail, looking for a dkms.conf file that didn't exist.

  • the dkms status now correctly shows the installed status of bbswitch, nividia, and virtualbox dkms softwares.

  • future kernel upgrades should properly build/rebuild the remaining bbsswitch, nividia, and virtualbox dkms software modules.

  • we also checked that the virtualbox-dkms was the correct version for the installed virtualbox.
