Switching to any other virtual terminal showed the same as F6, just a frozen update in progress with all the output there.Īfter attempting to get another shell (I couldn't), attempting to kill or suspend the update (I couldn't), open up Terminal in one of my GUI terminals (I couldn't), or just reboot or shut down from the GUI terminal (I couldn't), I held down the power button until the computer shut off, and started it up. The applications that were already open (Nautilus and Solitaire) worked fine, but nothing else. The update froze-and I couldn't open any applications in either of my graphical terminals. I was doing this in a virtual terminal (Ctrl-Alt-F6) and I had two graphical terminals open at the same time (F7 and F8). It downloaded everything and went about unpackaging things and installing them. I was upgrading my laptop from 16.04 to 18.04 using the do-release-upgrade command.
