Some observations with Ubuntu 22.04 Jammy Jellyfish and pat 0.12.1-1:
* The ubuntu package (-1) is not built with ax25 support, so it doesn't work with packet winlink (this might be a legit bug for the packager)
* There is no pactor support (appears to be removed on purpose)
* The ubuntu package (-1) will automatically upgrade over the developer's debian package by default!
* The command `apt-mark hold pat` can be used to avoid automatically updating to the Ubuntu package.
For these reasons, I prefer to use the developer's version of the package; I might consider the distro package if they fix ax25 support.
Unfortunately last weekend, I had done a fresh install of ubuntu 22.04, downloaded pat .deb from github and got everything set up for a training exercise on Saturday... except when I started pat it said command not found: /usr/bin/pat; to my horror, ubuntu automatically updated my pat installation overnight, breaking it in the process (no ax25 support). I couldn't participate in the exercise with that machine until I found internet access and re-downloaded pat from github releases.
Now I make a point to `apt-mark` everything that I manually install.
