Is there a generalised way to find out what package caused the installation of a command?
Open a terminal and try the following commands:
dpkg -S 'command name'
dpkg -S /bin/ls
You can also obtain detailed status information about coreutils package, enter:
dpkg -s coreutils
Package: coreutils Essential: yes Status: install ok installed Priority: required Section: utils Installed-Size: 9040 Maintainer: Ubuntu Core Developers Architecture: i386 Version: 5.97-5.3ubuntu3 Replaces: textutils, shellutils, fileutils, stat, debianutils (<= 2.3.1), dpkg (<< 1.13.2) Provides: textutils, shellutils, fileutils Pre-Depends: libacl1 (>= 2.2.11-1), libc6 (>= 2.6-1), libselinux1 (>= 2.0.15) Conflicts: stat Description: The GNU core utilities This package contains the essential basic system utilities. .

there is another one method, maybe a little silly, but faster than previous ones :) just mistype a command and you will get correct command name and package it came from.
pawel@pawel-desktop:/var/www$ sfn No command 'sfn' found, did you mean: Command 'sn' from package 'mono-devel' (main) Command 'sfc' from package 'syfi-bin' (universe) Command 'svn' from package 'subversion' (main) sfn: command not found
From the command name you can use the 'type' and 'dpkg' commands to determine the package which is responsible for their installation. For example to find out which package installed the command 'who' you could do the following commands at a command prompt:
$ type who who is /usr/bin/who $ dpkg -S /usr/bin/who coreutils: /usr/bin/who
Now for a completely different approach.
Go to packages.ubuntu.com and follow your nose. In particular, scroll down to "Search the contents of packages" and enter the file name or system command.
