Some words about deb packages on our website.
I do install deb packages like this:

sudo apt-get install ./generic-finder_1.00-20_all.deb

I do uninstall the program in this way:

sudo dpkg -r generic-finder

This worked for me in Ubuntu 18/20/22. Generic Finder is written in C++ 17 and make use of Qt 5.9.5...5.15.0
GF's dependencies are resolved by apt on Ubuntu 22.04 automatically.
GF can be started with ' gf ' in shell or mouseclick on Gnome Menu Icon 'Generic Finder'

More work is need if we want the program to be installed on older versions (Ubuntu 18.04) ...
