I have previously upgraded from 16.10 to 17.04 but it didn't go well at all.
I used deja-dup to restore my settings and this resulted in a messed up connection manager, the inability to change the wallpaper anymore, and random app crashes.
What is the recommended way to upgrade Ubuntu? And if reinstalling from scratch, what is the point of the deja-dup backup if it can't be restored without creating issues? How else do you migrate your settings?
