I want to keep my /etc/apt/sources.list clean and I'm looking for a way to look for a package in a repository before adding it to my system. Thanks in advance.

You can browse the link to the repository in your browser. if you look there for the Packages files (usually Packages.gz and Packages.bz2) in the correct folder under dists, you can download that file and uncompress it. It contains a list of all the packages of the archive.


For example; if the repository is: http://ca.archive.ubuntu.com/ubuntu/; you could simple enter the site with web browser and look for the package you want. The packages are in "pool" directory.

Example: http://ca.archive.ubuntu.com/ubuntu/pool/main/a/alien/
