I did the 18.04 > 20.04 > 22.04.3 in-place upgrade. I followed this fantastic comment: Version 60 for Ubuntu 22.04 is released - #46 by mouse
In addition, I had to manually remove the blinker 1.4 Python package that came with the upgrade.
sudo rm /usr/lib/python3/dist-packages/blinker-1.4.egg-info
sudo rm -rf /usr/lib/python3/dist-packages/blinker
If you can share what errors you’re encountering, we can probably help.
