Remmina Remmina

I have two computers that I installed Zorin OS on. The objective was to get the trial system up and running functional before I totally destroyed Windows 10 on my main system. without a doubt Zorin is the best . once I killed Windows 10 on my main machine and installed Zorin OS. I noticed something on my main System that I did not see on the other computer and that is Remmina so I used terminal to install Remmina onto the trial computer. once that was accomplished
I go to the dash and there you have it. Remmina Remmina let down your golden hair. The program that was lost? oops now they're both there. I was using cmd found online for snap through the terminal as the pgm does not show up on software store and trying to uninstall one of the two doesn't look promising.
All that to ask this is there any way to determine where these apps are coming from in terminal

I found it strange rhat you had to install Remmina at all as it has been present since Zorin 15.

Remmina comes preinstalled by default as APT Package. When you want get rid of both, the APT and the Snap Package:

APT: sudo apt purge remmina

Snap: snap remove --purge remmina

I was unaware of the fact that it was part of the pkg the fact was I had used my iso burn flash drive to install Zorin on both computers the only time Remmina showed up was on the last install there was no icon of Remmina on my inspiron one 2020 the first computer that I installed Zorin on I got hit with two Icons of Remmina on my dash once I installed it. clearly it was there all along. now I want to figure out how to remove one of and if necessary both in order to reinstall just one

nope just the one I installed

You can list the installed applications with the following commands:

apt list --installed
flatpak list
snap list

Each will produce a list of the installed applications managed by their respective package managers. The first one will list also all pre-installed programs and libraries, so it will be quite lengthy output. You can narrow it down by piping the output through grep:

apt list --installed | grep -i remmina

Hi, take a look at Logs, that should indicate when you installed Remmina second one, and hopefully indicate which package format.
