I have VirtualBox running as an unprivileged user on a RHEL 7.4 server with no GUI, phpvirtualbox is installed on this machine. I've recently upgraded to 5.1.26 and I'm trying to install the extension pack so I have console access to my VMs which are mostly used as build machines.
Trying to install as the unprivileged user gives the following error:
Code: Select all

I've seen this issue before and I'm pretty sure it's a permissions problem but can't for the life of me remember how to solve it. Can anyone shed any light?
Thanks,
DH
