[Bug 1773663] Re: I cannot upgrade from ubuntu 16.04 to 18.04

[Jean-Baptiste Lallement]

Thanks for the report.

Xorg stack from the oibaf PPA are blocking the upgrade. Please revert to
official version of these packages and try the upgrade again.

I'm closing this report because it is not a bug with Ubuntu but do not
hesitate to submit any bug you may find.
