I upgraded from Fedora 20 to Fedora 22…

…and surprise, surprise! Firefox is what we’re going to have problems with.

I have no idea how this happens and it definitely is annoying.

Otherwise, upgrading using FedUp from 20 to 21 and from 21 to 22 only involved removing some conflicting packages prior to the upgrade and installing them again later.

Somehow it re-enabled the display manager that I don’t use though; I’ll have to disable it again later. And trying to install VirtualBox results in some kind of a conflict:

Error: nothing provides kernel-uname-r = 4.0.8-300.fc22.x86_64 needed by kmod-VirtualBox-4.0.8-300.fc22.x86_64-4.3.30-1.fc22.x86_64
