I can reliably observe the problem in a groovy VM. However, contrary to what Séb is observing, "sudo ubuntu-drivers install" raises an error:
ubuntu@groovyvm:~$ LANG=C sudo ubuntu-drivers install Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: virtualbox-guest-dkms-hwe : Conflicts: virtualbox-guest-dkms virtualbox-guest-x11-hwe : Depends: virtualbox-guest-utils-hwe (= 6.1.8-dfsg-1ubuntu20.10.1) but it is not going to be installed Conflicts: virtualbox-guest-x11 E: Unable to correct problems, you have held broken packages.
