upgrade to 19.04

[Cristian Bungau]

I am trying to upgrate to Ubuntu 19, mainly because my Ubuntu 18 installation went crazy, and the Intel graphics driver has decided to play tricks. I can now see many small (dashed) horizontal balck lines on my monitor. But the upgrade fails and I am asked to use ppa-purge to get read of unofficial software. I have removed all unofficial software I could find, but it is still not letting me upgrade.

You still have packages installed from a PPA, even though you may have disabled the PPA, so the upgrade is failing to calculate. From VarLogDistupgradeAptlog.txt:

Broken xserver-xorg-video-nouveau:amd64 Depends on xorg-video-abi-23:amd64 < none @un H >
  Considering xserver-xorg-core:amd64 25 as a solution to xserver-xorg-video-nouveau:amd64 5
  Removing xserver-xorg-video-nouveau:amd64 rather than change xorg-video-abi-23:amd64

You'll need to reenable the PPA and then use ppa-purge to disable it and remove the packages which came from that PPA.

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 package version numbers greater than the release to which you are upgrading. You can revert the PPA by installing the ppa-purge package from the official Ubuntu archive and then running 'sudo ppa-purge oibaf'. After that you try upgrading and again and if it still fails open a new bug report. Thanks and good luck!
