I upgraded to Ubuntu 16.04 about and hit this tex-common problem. I found a solution
here, which needs me to comment out lines to cancel out lines 2093 and 2094. I have absolutely no idea how to do that...can anyone help me out.
Edit: I've just fixed it...I ran through the steps I'd done before and I got a list of files and an option to auto remove them...so I did and the problem is sorted! I'm well chuffed with myself
An 'old dog' can learn new tricks; I love Linux and hope to move on from Ubuntu.
