It's high time I upgrade Ubuntu from 18.04 to 20.04! But I don't get very far before the process aborts without an error message. Is there a log file I can check for further information?

Apparently, there's /var/log/dist-upgrade/main.log. All it shows is that Quirks.focalPostInitialUpdate "called abort".

Other files in /var/log/dist-upgrade reveal nothing either.
Additional info:
- Windows was brought up to date beforehand (in case it was some WSL issue).
sudo apt update && sudo apt upgrade did not help.
