[GNC] Install Gnucash on Debian

[Mike stagl]

I realized I had installed GnuCash on my Debian system using apt-get and a repository.  The latest version for which this works is 2.6.15.

How do I install GnuCash 3.3 or higher on my Debian system? I'm hoping the answer isn't to build my own with cmake... I've never done that before and am a little intimidated by the process and checking dependancies.

Is it possible to download the Ubuntu .deb? Would that work, in theory?

Thanks to all the contributors,

Mike
