[GNC] GnuCash 3 for Ubuntu Studio 22.04 LTS

[rsbrux]

According to https://wiki.gnucash.org/wiki/Ubuntu, “GnuCash 4.8 is included in Ubuntu 22.04, released April 2022 https://packages.ubuntu.com/jammy/gnucash”.

I was running GC 2.6.19 under Ubuntu Studio 18.04 and I have read on this mailing list that I will need to migrate to GC v 3.x before I can migrate to GC 4.

I would therefore like to install GC 3.8b. What is the easiest way to do this?

Is there a repository I can add to Discover that I can pull it (or at least some stable 3.x version) from?
