Hi!

It seems like you've installed 3rd party drivers. Please remove them and see if the upgrade succeeds then.

Quoting https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

=== Upgrading to a newer Ubuntu ===
It is *strongly* suggested to remove all packages from this PPA before updating to a newer Ubuntu release. See the section "Revert to original drivers" later on.
Then, after the upgrade, you can add again this PPA.

=== Revert to original drivers ===
To revert to standard Ubuntu drivers type the following in a prompt shell:
$ sudo apt-get install ppa-purge
$ sudo ppa-purge ppa:oibaf/graphics-drivers
