The Ultimate Debian Database (UDD) gathers a lot of data about various aspects of Debian in the same SQL database. It allows users to easily access and combine all these data.

Data currently being imported include: Packages and Sources files, from Debian and Ubuntu, Bugs from the Debian BTS, Popularity contest, History of uploads, History of migrations to testing, Lintian, Orphaned packages, Carnivore, Debtags, Ubuntu bugs (from Launchpad), Packages in NEW queue, DDTP translations.

For more information, please contact us on #debian-qa or debian-qa@lists.debian.org (mailing list subscription and archives).

Connecting to and using UDD

udd.debian.org is running on ullmann.debian.org. It accepts direct SSLed connections from master, coccia, quantz (qa) and respighi (release) (firewall config).

If you want to know precisely when a specific data source is updated, you can take a look at this config file, or at the current UDD status.

If you do not have access to the required machines, you can access the public UDD mirror directly from your own machines:

Credits and citing UDD

UDD started as a Google Summer of Code project by Christian von Essen (Neronus), co-mentored by Lucas Nussbaum, Stefano Zacchiroli and Marc 'HE' Brockschmidt. It is now mainly maintained by Lucas Nussbaum, with help from others.

Improving UDD

If you want to help improve UDD, you can set up your own instance as described on UltimateDebianDatabase/Hacking. You can report bugs against the qa.debian.org pseudo-package, using the udd usertag and user qa.debian.org@packages.debian.org. (list of bugs ; or list of bugs using UDD)

When reporting bugs by email, it means using the following pseudo-header:

Package: qa.debian.org
User: qa.debian.org@packages.debian.org
Usertags: udd
