In recovery mode, after a failed system upgrade to Ubuntu 24.04, the photo below shows the information that appears on the screen. There appears to be no access the command line (I tried Ctrl+Alt+F3). I would appreciate any advice on what to do next. This is an iMac from 2015.

The procedure that worked to resolve this was:

Use Live media and re-install the previous ubuntu system (in my case this was 22.04.2 LTS) rather than the targeted upgrade version (24.04 LTS).

Steps taken to get access to the Live USB are set out in the answer given by The_Loud.speaker in this post:

Is there a way to boot from usb through grub menu?

Note: These steps need to be followed carefully because it was only possible to use a limited range of bash commands. The screen stated: Minimal BASH-like editing is supported.

This allowed me then to use the GUI to re-install the 22.04.2 LTS system.

I then followed the upgrade steps when prompted, and 24.04 LTS was successfully installed.
