Ubuntu interrupted an upgrade due to a locally changed grub file. I selected the option to open a new terminal to see the differences. It just kicked me back to the existing terminal as root instead. I closed that terminal because I typed something that kicked me out of root. How do I get back to the upgrade process? dpkg is locked. I don't have the screen command. It's VERY similar to this: Hit Ctrl+c during do-release-upgrade. Did I break it?. None of those solutions work.
Checking the version, I get back 19.10, so I cannot just try do-release-upgrade again.
