Detailed view of installed packages?

[jbads]

I have been looking around for ways to view installed packages in a more detailed way. I went into Muon, which shows applications to remove but that is about it. I was just wondering about this because over the weeks of use I have installed many packages to get certain things to function. But I would love to be able to remove packages I am not using. How do you guys cope with this? Is going into sources in Muon the best I can do?

Are you using muon discover or muon package manager? Package manager will give you much more information. Many people prefer synaptic package manager, although it pulls in lots of gtk dependencies when you install it, whereas muon is a Qt app.


From the commandline, you can use dpkg --get-selections to list all installed packages. You can sort the output by piping it to grep like so:

dpkg --get-selections | grep apache2

There are lots of other commands or viewing additional information about a package, it's difficult to know which to recommend without knowing what you're after. Here are a couple:

$ apt-cache show apache2

Yeah, not clear what your goal is, but ...

do you mean, clean, autoclean, autoremove? See man apt-get.

In MUON Package Manager, you can click on an installed package, and the tabs below show dependencies and installed files?

[Qqmike]

If you are using Muon Discover, enter Muon Package Manager in the search box and it will show up --> click Install etc. (which, I think you probably know that).

[jbads]

Yeah I was using Muon Discover which gives you almost no information. Went in and installed Muon Package Manager now. Thank you feather for providing those commands as well . Installed MakeMKV, and now I can play Blu-ray discs in VLC. Strangest thing I have ever seen.

if you install muon

sudo apt install muon

this is the package manager ,,,,,,you can sort by "installed"

I would use the command line for this as you can do a -s (simulation) with the remove option to see what elce is going to get removed ,,,some times removing one package will want to remove a lot more as well.
