How to remove Barrier & Synergy app from Ubuntu 20.04
I bought Synergy ~18 months ago before I had heard of Barrier, but when I heard of Barrier and I had 2 new machines I just built, I thought I'd give it a try. Well it wouldn't work on either of these, so I tried installing Synergy. At the time the system wouldn't allow me to remove barrier (even after ending the process) and now it seems it can't be found in the installed packages/software list.

I let the machines sit for like 5 months and now I'm back trying to get them running. They are fully updated version of Kubuntu 20.04 if that matters.
I tried removing barrier a number of different ways and I get

USER@MACHINE:~:~ sudo apt-get purge barrier

Package 'barrier' is not installed, so not removed
The following packages were automatically installed and are no longer required:

I tried a couple other methods yesterday but I forget what they were, but it always seemed like it couldn't be found. (and it still loads on boot even though it's not in the Startup/Autostart programs list)

SO I ran this command:
sudo apt list --installed > packages.txt
and then searched the text file for anything related to Barrier or Synergy and nothing comes up (of near 500 packages)- so I'm at a lost as to where they might be hiding. I don't recall how I installed them, if it was "apt install" or used the snap/snapd function - or if I installed from a .deb file.

Either way this thing is being a real PITA at times and it's locking up my machine when it randomy pops up on screen telling me it's looking for a server or a client.

If there is anything I can do to get this software removed, I'd really appreciate some tips on this! Thanks!

@KDE5FAN Could you post the output of ps aux | grep -i barrier after logging in? If you can capture the same when barrier starts bothering you that would be a bonus, but likely not necessary.

I would also do this: find / -iname "*barrier*". This would find all files related to Barrier and maybe we'll see what the installation method was.

Thanks!
