This sounds very useful! I googled but didn't find much - perhaps I did not use the right terms. Can you please post some links that point me in the right direction?
Rather than Ctrl+Alt+F1 (which switches to a TTY), you can open a Terminal instead and run 'sudo -i' to get a root shell.
Replace 'sda1' with your root disk (you may have LVM enabled, and definitely if you have full disk encryption). If you don't have disk encryption, run 'pvscan' and see if it reports anything.
To get the update to finish, you can run 'dpkg --configure --all'.
