Comment 5 for bug 1875523

Hey @capitaotsunami

I was able to reproduce your problem. After removing 'python-gi' the upgrade seems to be working.
There seems to be some kind of broken dependency between 'python-gi' and 'libgirepository-1.0-1'

Could you please try to confirm this, by running the following commands?

sudo apt remove python-gi
sudo do-release-upgrade -d
