While trying to upgrade python, I've somehow managed to damage something in my Ubuntu setup. I first noticed that the terminal app had disappeared, and using ctrl-alt-Fx wouldn't give me a command line to reinstall it.
I then tried rebooting, but now it won't boot to GUI. I can log in and use the command line, but I have no network access so trying to reinstall ubuntu-desktop fails.
I've tried fixing the packages in recovery mode, and running boot-repair off USB, but neither of these have helped.
I do get a couple of warnings before it fails:
blacklist: Problem blacklisting hash (-13)
usb 5.1.4: Failed to query (GET_INFO) UVB control 5 on unit 1: 0 (exp.1 )
usb 5.1.4: Failed to query (GET_INFO) UVB control 5 on unit 1: 0 (exp.1 )
The blacklist error seems to suggest something to do with UEFI/BIOS, but this has not changed since I got the motherboard and the PC's been working fine for several years.
Does anyone have any suggestions of what I can try before I resort to reinstalling?
Many thanks
