I'm trying to upgrade from 16.04 to 18.04 with the GUI tool. It's reached this state below and has been stuck there for hours.

enter image description here

If I try restart, it warns me an application is restricting this action unless I use Administrator override.

Interestingly, the panel seems to get life again and gets color every 20 or so minutes.

    Well it seems the threat of restarting worked. It completed its steps, albeit silently. Thanks ) – SelfishCosmonaut Dec 2 at 9:53
