I have Ubuntu 16.04.3 LTS amd64 host with Oracle VM VirtualBox 5.1.30-118389~Ubuntu~xenial from their repository.
I have created Ubuntu 16.04 LTS amd64 guest in VBox. Installed all updates here with aptitude. Also I installed
virtualbox-guest-x11 (version 5.0.40-dfsg-0ubuntu1.16.04.2 from multiverse repository) to guest.
Why this happen?
Should I install the same version (5.1.30) of guest additions as host VirtualBox?
