I have installed VirtualBox from the official Ubuntu repository:
virtualbox
virtualbox-qt
virtualbox-ext-pack
After adding the official Oracle VirtualBox repository:
deb http://download.virtualbox.org/virtualbox/debian xenial contrib
And its key:
https://www.virtualbox.org/download/oracle_vbox_2016.asc
I can now install virtualbox-5.2
. But it removes virtualbox-qt
and virtualbox-ext-pack
.
How can I install VirtualBox 5.2 and have the GUI and the extension pack?
