Comment 8 for bug 1772246

Upgraded two more instances (a quite old 32-bit Lenovo Thinkpad and one 64-bit desktop) from Lubuntu 16.04 to 18.04 - both without any PPA's installed. Didn't experience any problem at all. My own setup is a little customized to my needs. Most of the previously installed PPA's have been moved to isolated containers (e.g. snap) - others are still required and I cannot move them (yet). However I think it is save to close the issue and focus on more important stuff to further improve the distro. :)
