Copying in a relevant comment from Adam Conrad in the original bug report: This isn't a bug in software-properties. What I can't decide is if it's a bug in virtualbox-guest* or ubuntu-drivers-common. Basically, here's what's happening:
1) The virtualbox-guest* packages have a modalias for the "guest services", but not the VGA controller. 2) We pulled the DKMS drivers into the kernel. 3) The above situation confuses ubuntu-drivers-common, which really wants to install vbox-dkms, but we have it builtin. 4) Nothing wants to install vbox-x11, which we actually want. So, the lack of modaliases on vbox-x11 is definitely a vbox bug, and the dependencies are also a bit strong between vbox packages (we should drop some recommends to suggests, to stop trying to forcefully install compilers to get an X driver). That said, we might also want to quirk the ubuntu-drivers-common detection a bit to either hide vbox-dkms altogether, or actually let us use it if it's a potential upgrade. Currently, neither of these options is in play, and we see it, but it's greyed out, which is amazingly confusing. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ubuntu-drivers-common in Ubuntu. https://bugs.launchpad.net/bugs/1878553 Title: Ubuntu could not install Virtualbox Guest addons Status in ubuntu-drivers-common package in Ubuntu: Confirmed Status in ubuntu-drivers-common source package in Groovy: Confirmed Bug description: It seems that Ubuntu is not able to install the VirtualBox Guest add- ons even Ubuntu is able to detect it.
