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. ** Package changed: software-properties (Ubuntu) => ubuntu-drivers- common (Ubuntu) ** Also affects: virtualbox (Ubuntu) Importance: Undecided Status: New ** Changed in: virtualbox (Ubuntu) Importance: Undecided => High ** Changed in: virtualbox (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to software-properties in Ubuntu. https://bugs.launchpad.net/bugs/1434579 Title: Unable to install VirtualBox Guest Service in 15.04 Status in ubuntu-drivers-common package in Ubuntu: Confirmed Status in virtualbox package in Ubuntu: Confirmed Bug description: It is not longer possible to select VirtualBox Guest Service in 15.04. The only options available are: * Continue using a manually install driver * Do not use the device The option 'Using x86 virtualisation solution - guest addition module' is no longer selectable. See the attached screen shot. This is from a fresh install of Ubuntu MATE 15.04 daily (20th March) and no drivers have been manually installed. In light of the Virtualbox issue where new installs on Virtualbox have a resolution of 640x480 (https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1368784/) this is going to be a frustration for many users.
