If DD breaks this compatibility intentionally for important library upgrade etc, there is usually announcement to the debian-devel mailing list etc.īefore a set of packages are moved by the Debian archive maintenance script from the unstable archive to the testing archive, the archive maintenance script not only checks the maturity (about 10 days old) and the status of the RC bug reports for the packages but also tries to ensure them to be compatible with the latest set of packages in the testing archive. (Although, the word "main section" may sometimes be used to describe the Debian archive area named as "main".)Įvery time a new upload is done by a Debian developer (DD) to the unstable archive (via incoming processing), the DD is required to ensure uploaded packages to be compatible with the latest set of packages in the latest unstable archive.
In the stricter Debian archive terminology, the word "section" is specifically used for the categorization of packages by the application area. The history of codenames are described in Debian FAQ: 6.2.1 Which other codenames have been used in the past? Here are some basic precautionary measure ideas to ensure quick and easy recovery from bugs in Debian packages. Even though the unstable suite of the Debian system looks very stable for most of the times, there have been some package problems and a few of them were not so trivial to resolve. The unstable suite is good for debugging packages as a developer but tends to expose you to unnecessary risks for the normal Desktop usage. The use of the unstable suite isn't recommended. The Debian user and developer mailing list are good sources of information for this, too.

Manually update this codename in the " /etc/apt/sources.list" to the new one only after assessing situation by yourself for about a month after the major suite release. Set the codename corresponding to the testing suite (currently " bookworm") in the " /etc/apt/sources.list". The packages in the testing suite are updated frequently enough to offer all the latest features. Use the testing suite since it is practically the rolling release automatically managed by the Debian archive QA infrastructure such as the Debian continuous integration, the source only upload practices, and the library transition tracking.
