[Bug 1703809] Re: i am getting this problem while updating from 16.10 to 17.04

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. Thanks.
