Been there but it was 1 week later. 4 years of severe depression (and still going) and I haven’t lost yet so I got that going for me.

My local library uses thin clients with virtual desktops but I have a feeling the library system here is funded much better than the OP’s library.

Software is fine but OS wise there are lots less than there was 5 years ago and it only going to get smaller but at least there Debian.

They could do a thin client type of deal and just virtual desktops that get deleted at the end of the session. If they are on 32bit hardware that really limits options on operating systems but a single backend computer hosting virtual desktops can be a donated 64bit PC/Server.
