It has taken me a few months, but I have finally finished switching my kids' school office to Linux (except the Accountant computer, which needed Quickbooks, so it is on Windows 10).
I installed Ubuntu 20.04, with Dash-to-panel and Arc Menu, and Papirus Icon theme.
Everyone seems to like it, (or at least accept it). They are all on Google Docs, so they really just need a platform to launch Chrome Browser.
The one strange thing I have run into: the office has one of those huge monster Printer/Scanner beasts. It works fine, but if I installed the printer while the computer was connected to the Office Network, then the printer dialogue takes ages to load (longer than a minute).
Some of the computer I set up at home, so I just installed the printer without it being on the local network. Those computers the printer dialogue just pops up.
I have not been able to figure out what the difference is.
