[Andrea Righi (arighi)]

Attached debdiff disables vboxvideo in virtualbox-guest-dkms and forces the usage of the mainline vboxvideo. In this way we can prevent the build errors from happening. A nicer solution would be to disable vboxvideo only in kernels >= 5.11, but this shouldn't be a problem in hirsute (this change should be valid both with all kernels >= 5.10).

[Launchpad Janitor (janitor)]

This bug was fixed in the package virtualbox - 6.1.18-dfsg-3ubuntu1

---------------
virtualbox (6.1.18-dfsg-3ubuntu1) hirsute; urgency=medium

  * Support linux 5.11 (LP: #1917581):
    - drop vboxvideo and use the mainline driver
