[N.B. My first post - guidance welcomed]
We have a small local network of users (5) on deb-based systems and would like to maintain an index of apps installed.
How can we, programmatically, inventory a given Linux desktop installation for all applications added by the user
Optimally, this would include distro repos but, also; appimage, snap & flatpak. It would exclude more container-ish elements such as docker & lxc/lxd.
