Public bug reported:
Ubuntu Cinnamon 20.10 does not install nor update the Linux headers,
that are required for the Virtualbox Guest Additions. The upgrade from
Linux 5.8.0-18 to 5.8.0-19 went wrong after reboot, because the screen
was using the default 800 x 600. It was not possible to update to my
standard 1920 x 1080, because it was missing from the list of supported
resolutions, so I compromised on 1680 x 1050.
I used Synaptic again to reinstall the Linux headers and after that the
installation of Virtualbox Guest Additions went as as expected and
everything was OK. Ubuntu itself does NOT have this problem, it is
specific for Cinnamon.
