Does apt on 20.10 have a virtualbox package?

I see that apt install virtualbox virtualbox-dkms has worked on previous releases but on 20.10

 apt install virtualbox

 Package virtualbox is not available, but is referred to by another package.
 This may mean that the package is missing, has been obsoleted, or
 is only available from another source

 E: Package 'virtualbox' has no installation candidate

apt search doesn't find anything like it.

  • Yes.. it's found in multiverse'so your package tools won't find it unless you have multiverse enabled - help.ubuntu.com/community/Repositories/Ubuntu (if you use rmadison you can go beyond your enabled repositories or actual release, but that tool isn't instaled by default)

  • @guiverc Yes. My sources.list had no multiverse entries so I added them in using the universe lines as template. Then with apt update and apt install virtualbox virtualbox-dkms the application installed. thanks Dec 4, 2020 at 4:30

Note that Virtualbox is in the multiverse repository. Since your apt cannot locate the package, you likely do not have the repository enabled. Here's how to enable it

  • Ah. The multiverse lines were missing from my sources.list. So I copied the universe lines and changed universe to multiverse. VBox then installed. Interesting that I've been installing VBox for years without having to do this. So something happened to my sources.list during do-release-upgrade. Dec 4, 2020 at 4:27
