Like GetDeb? Now you can get their packages from a repo
One of the best ways to get updated software for Ubuntu Linux, as well as other Debian-based distros, is from GetDeb.net. I can’t tell you how many times I’ve used their packages to get an update that isn’t available from official Ubuntu repositories or PPA’s.
They’ve recently launched an updated site for users of Ubuntu 9.04 and newer, and one of the great new benefits is that they now have a repository you can add to your sources.list. You can either manually add their repo and key, or you can do it even more easily by downloading their getdeb package which will automatically add their repo and repo’s PGP signing key.
