General How-tos


Debian Releases

  • Stable (currently "Sarge") = this is the latest official release of the Debian GNU/Linux distribution. This is stable and well tested software, which changes only if major security or usability fixes are incorporated. This realease is considered by many too old to be used as desktop environment, it is used mainly for servers and mission critical systems.
  • Testing (currently named Etch) = contains packages that are intended to become part of the next stable distribution. There are strict criteria a package in unstable must obey before it can be added to testing.

Apt-get terminology

  • Unstable (always "Sid") = developement branch of Debian. Contains the most recent packages in Debian. Once a package has met our criterion for stability and quality of packaging, it will be included in testing. Packages in unstable are the least tested and may contain problems severe enough to affect the stability of your system.
  • Update or Reload in Synaptic = getting information about the current packages available on the Debian and Mepis servers.
  • Upgrade = getting and installing new version of a package.

Distribution Production Stages

Alpha = "The first testing stage of a new program. The alpha stage occurs before a program becomes a beta version." Sometimes is used for stages of the product that are tested inhouse, not released for outside testers. Beta = "The last software testing phase before a production rollout." "A version of an application that is made available prior to the official release for the purposes of testing."

Other explanations for the terms used:

  1. Snapshots/Experimental -- it represents a sneak peek only.
  2. Alpha = represents the first stage of developement (intended for experienced users that want to test and hunt for bugs).
  3. Beta = represents the second stage of developement, usually contains less bugs than Alpha (intended for curious public, but not to be used in "production").
  4. RC (Release Candidate) = proposed final product, it is going to be release as it is if no major bugs are founded.
  5. Final or stable release -- to be used by all, experienced and newbies alike.
