Tried updating my system today. The updates went through, but the following error persists when I use sudo apt autoremove or sudo apt upgrade

sudo apt autoremove

0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

I am using a custom kernel

uname -r
5.8.9-050809-generic

I googled the first error that mentions anbox-ashmem and I saw some very complicated (for me) discussions, hence I decided to post here to avoid breaking my system. I can restart and use everything normally at the moment.

sudo dpkg-reconfigure [package] seems to be a popular fix for this, however it doesn't always work.

Solution from and possible duplicate of: `Error! Could not locate dkms.conf file`

  • I am not sure what package I need to reconfigure. I ran one of the commands from the thread you have linked, namely for i in /var/lib/dkms/*/[^k]*/source; do [ -e "$i" ] || echo "$i";done, which supposedly identifies the offending modules. It returned /var/lib/dkms/anbox-ashmem/1/source and /var/lib/dkms/anbox-binder/1/source, but I don't know what to do with these. – ThunderBiggi Oct 12 '20 at 06:49
  • Remove and reinstall maybe? Not really sure how critical anbox is to the OS nor what it really does. – Vasilisa Oct 12 '20 at 14:43
