OK, this is has got to be one of the messiest upgrades I've encountered since I first started using Ubuntu in 2006. Besides everything else that has gone wrong, like not even being to shutdown without hitting the PC's button, it seems I don't have permission on my system to do just about anything. My first inkling there was some kind of permissions screw up was when I went to install updates after the notification popped up, and it told me I wasn't authorised to use the Software Updater (same with Muon in my KDE desktop). Sure, I can run update-manager as superuser to get around that, but this permissions screwup is affecting some of the simplest things I used to take for granted.
Now I can't even mount and use my removable drives like I did before the upgrade, not without running Nautilus as superuser (make that Dolphin, as unlike the former, this will show the removable devices and other partitions in the left pane in superuser mode). And just when I thought it couldn't get any worse, inserting a DVD (or rather clicking on it to mount it via the shortcut in the left-pane of any file manager) gives me the error message: "Unable to access "DVDVIDEO". Not authorized to perform operation."
At first I thought the mounting failure was just in KDE, as I've used that the last couple of days since it isn't as screwy as Unity and Gnome Classic, but logging back into Ubuntu/Gnome shows it is system-wide. Does anyone know how to rectify this? And while we're at it, why Shutdown no longer actually turns off my computer? Many thanks in advance.
