On Ubuntu 21.04
During a system upgrade, I opened a configuration file in my editor during which my editor crashed, which in turn made apt crash mid upgrade.
Now, when I rerun sudo apt-get upgrade, I get a large number of errors relating to python 3.9 being missing and advised to run apt --fix-broken install:
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution)
When I run apt --fix-broken install however, an error occurs when install python3.9-minimal:
