Public bug reported: Trying to upgrade from 17.04 to 17.10, I am getting the message "Could not calculate the upgrade".
I have seen the bug https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1069160 which seems similar, but refers to earlier releases (and is marked as invalid), so I am reporting a fresh bug. Bug 1069160 was resolved by a couple of people by removing xserver-xorg-video-nouveau, which I also have installed, but attempting to remove this will also remove xserver-xorg-video-all, and then makes a whole list of xserver-xorg-packages "no longer required", including the one for my graphics card - so I am reluctant to remove this package. I cannot work out whether I have unsupported packages which are preventing calculation of the upgrade (I had a look through the apt.log but couldn't work out where the error was). Thanks in advance for your help. I've attached the apt.log file, and will attach the main.log file in a comment.
