VirtualBox has been working on this Ubuntu host for years.

Now after the do-release-upgrade from 20.04 to 20.10 it is having a trouble:

 sudo apt install linux-headers-$(uname -r) Reading package lists... Done Building dependency tree Reading state information... Done linux-headers-5.8.0-31-generic is already the newest version (5.8.0-31.33). linux-headers-5.8.0-31-generic set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. sudo apt install virtualbox virtualbox-dkms [sudo] password for stephen: Reading package lists... Done Building dependency tree Reading state information... Done virtualbox is already the newest version (6.1.14-dfsg-4). virtualbox-dkms is already the newest version (6.1.14-dfsg-4). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. stephen@acer:~$ vboxmanage list vms WARNING: The character device /dev/vboxdrv does not exist. Please install the virtualbox-dkms package and the appropriate headers, most likely linux-headers-generic. You will not be able to start VMs until this problem is fixed.
