Welcome. I'm not a ham, nor an expert on Ubuntu, though I've making it work
and enjoying it for 5 years.

Just a couple of thoughts... Are you using something from the repositories
(via Synaptic, Muon Software Centre or similar)? Surprisingly, many Windows
programs will run, but not always perfectly, on Linux by using Wine or a
virtual machine.

Your best friend is the search engine and there aren't many problems that
you won't find an answer for there by intelligent Googling.
