I have installed Virtualbox in the past by using;
pacman -S linux-headers
pacman -S virtualbox virtualbox-guest-iso
pacman -S vde2 net-tools virtualbox-ext-vnc
Then pasted the following;
gpasswd -a user vboxusers
I also installed QT4
Today I did a fresh install of Antergos, and tried to install Virtulabox 5.1 (as above) afterwhich it would not launch.
Any suggestions or help is appreciated in advance!
