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.
