I guess we probably should switch to 20.04 for the "older Linux" build. (Ubuntu 18.04 comes to end of support in April 2023 according to https://wiki.ubuntu.com/Releases)
It's probably a 1-line or 2-line change to switch the action over, but would be good to get other folks' views on when to do it (eg should we wait until closer to April 2023?)
