It can fail spectacularly if you have installed other software from PPA or anywhere else that has conflicting package names or versions. Also, I have much better luck upgrading from the command line with do-release-upgrade than using the GUI. I've had to reinstall systems when a X, GTK, or Gnome library was upgraded and then another package failed to upgrade leaving me with a system that was unusable.
