Most of the time when I want to try a new program, the package manager tells me that I also need to install certain dependencies. Figuring that the program will not work without these dependencies, I install all of them. Sometimes the program is good, other times the program doesn't work or crashes or I just don't like it.
How can I uninstall the program and all the dependencies that were installed with it?
Do I need to manually keep track of what gets installed when and where and what it needs to function?
I don't want a bunch of useless or otherwise unused programs cluttering up my computer, wasting space and slowing my system down. How can I get rid of it without guessing what I should and shouldn't need to keep?
Edited 2/4/2013 to differentiate question:
Is there any way to remove do this without resorting to the command line? I use Muon in kubuntu and Synaptic in lubuntu. Can neither one of these programs remove the software and dependancies that it installs?
