Thanks for your reply Brian. It would have been helpful for the error
to state something like "PPA's need revision" or something similar.
I'll check the link and hopefully be able to upgrade to 17.04
Have a great week.

Reviewing the files from your upgrade attempt you seem to have enabled
a
PPA that provides Xorg packages. This will prevent the upgrade as that
PPA contains different versions of packages essential to Ubuntu.  The
page, https://launchpad.net/~xorg-edgers/+archive/ppa, contains details
on to how to revert to the official Xorg packages for the xorg-edgers
PPA.  Instructions for reverting to official Xorg packages should be
similar for the PPA that you have enabled.
