Hi all,
I have been trying to get a Ubuntu VM up and running for weeks. I get the error below when starting the VM. I have tried changing permissions to be wide open, adding users, and so on, as per a number of articles I have read. Can anyone point me in the correct direction to fix this issue?
Thanks in adavance.
