After many hours of searching it turned out to be this......
Initial Root Password After Live CD Installation
After a Live CD installation, the root password is initially set to the same password as the user
account that is created during installation, but it is created in an expired state. In order to work
around the issue described in “Gksu Does Not Report Expired Password (6995127)” on
page 30, immediately change the root password upon your irst login. To do so, type the su
command and enter your password, followed by typing the new root password, twice.
$ su
Password:
su: Password for user ’root’ has expired
New Password:
Re-enter new Password:
su: password successfully changed for root
Everything works now. Hope this saves someone elses bacon 🙂
