The Debian Packaging System (DPKG/DEB) was developed about the same time as the RPM, and has the same features, although they are implemented differently. DPKG refers to the original software packaging utility. This has been superseded by more flexible and user-friendly utilities, so this branch is often referred to by the extension used by the package files: DEB ( . deb). Some distributions in this branch have corporate sponsorship (Ubuntu is the most notable) and thus, have a unified administrative utility, similar to SuSE's YaST for example. Others, such as Debian, depend upon third-party software to fulfill this function.
The most common distributions in this branch are Debian and Ubuntu. Most of the others in the branch, such as Mint and BackTrack, are derived from one of these.
