Debian Archive Signing Key to be changed
May 23rd, 2009
The Debian Project wishes to announce the change of the GNU Privacy Guard key used to digitally sign its archive reference files. Signatures are used to ensure that packages installed by users are the very same originally distributed by Debian, and have not been exchanged or tampered with.
Affected distributions are the Debian unstable branch (codenamed
as well as the testing branch (codenamed
Squeeze). The current stable
version Debian GNU/Linux 5.0 (codenamed
Lenny) and the current
oldstable version Debian GNU/Linux 4.0 (codenamed
Etch) will have
their ftpmaster signature updated too. The release managers signature
The currently used key will expire soon. The new key has already been
distributed via the debian-archive-keyring package. For users of the
current stable release Debian GNU/Linux 5.0 (codenamed
action is required from the user side, since Debian GNU/Linux 5.0
Lenny) was already shipped with the new key. Users of the
current oldstable release Debian GNU/Linux 4.0 (codenamed
ensure to have upgraded to the latest point release 4.0r8 which added an
upgraded package containing the new key. Users of Debian's testing
Squeeze) and Debian's unstable branch (codenamed
Sid) should ensure to have at least version 2009.01.31 of the
debian-archive-keyring package installed.
Starting with the next mirror update this evening and for the next three weeks the archive will be digitally signed by both the old and the new key. Starting with the 13th of June only the new key will be used.
For reference, the old key is:
pub 1024D/6070D3A1 2006-11-20 [expires: 2009-07-01] uid Debian Archive Automatic Signing Key (4.0/etch) <email@example.com>
And the new one is:
pub 4096R/55BE302B 2009-01-27 [expires: 2012-12-31] uid Debian Archive Automatic Signing Key (5.0/lenny) <firstname.lastname@example.org>
This key rollover is a normal maintenance task and was started in January. For security reasons Debian's archive signing keys regularly expire after three years.
