Please forgive me if I don't give enough detail. I am a new user. I recently tried to install GIMP (photo-editor) using the terminal and I think it required me to install flatpak which I don't really understand and shouldn't have installed it I guess, because now I can't do what I could before. I have since uninstalled flatpak but still have same problem.
Earlier, when I was using dpkg --list to get the name of a program I wanted to uninstall, I could see a full list of all installed programs. Now I just get this weird list that doesn't look like programs, and it starts in alphabetical order but only starting at the letter "L", e.g.
libgphoto2-6:a 2.5.16-2 amd64 gphoto2 digital camera library
is the first entry. And then,
zlib1g:amd64 1:1.2.11.dfs amd64 compression library - runtime
is the last entry.
It doesn't seem to be listing programs. Like, I have clementine installed and its no longer listed with that command. I am so confused.
To give another example, I installed and uninstalled a media player successfully earlier today using the terminal, using dpkg --list to determine said program's name. I can no longer see any real programs using this or similar commands I have found here.
EDIT: apt list --installed gives the same stupid incorrect list.
Maybe it's showing libraries instead of programs now??
