Debian Weather

The "weather" of a given Debian-based distribution is an indication of how safe it is on a given day to attempt some package installation/upgrade. A "bad day" is a day in which a sensible percentage of that distribution repository is not installable due to unsatisfiable inter-package dependencies. A "good day", on the contrary, is when most (possibly all) of the packages available in that distribution repository are installable. For more information see the thresholds below.

Available weathers

Weathers are computed architecture per architecture, on some Debian based distributions. Click on one of the links below to check today's weather for your distribution and architecture. Have a nice day!

Weather thresholds

Whether it is a good day or not is decided upon the percentage of non installable (binary) packages over the total number of available (binary) packages. Currently, package counts take into account only the main section of any given Debian distro/arch. The thresholds between the various available wheather statuses are given below:

clear<= 1%
few clouds<= 2%
clouds<= 3%
showers<= 4%
storm<= 100%

More information

For more information on the concept of "uninstallability" which is used by Debian Weather you can have a look at the EDOS formalization of inter-package relationships. An analysis of common reasons which rendere Debian packages uninstallable is available in the report about edos-debcheck experimental results.

edos-debcheck is available as an official Debian package, you can try it by yourself on the package set of your choice.
