I'm about to upgrade, or try the new Gramps 4.1 now that it has reached 4.1.1. I am a little confused though about the two python versions of the debs. Which is the best to use, the python2 or 3 version? I'm on a Ubuntu 14.04 stock system.
Use the one which goes with the Python your system
routinely provides you.
That said, historically speaking there have been more
Python2 users than Python3 users (as Python3 only
started being supported in 4.0.0), and as a result there
may be more hidden lurking Python3 bugs than hidden
lurking Python2 bugs.
