Public bug reported: 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.
