One year after the release of Debian GNU/Linux 6.0 alias “Squeeze” and nearly three years after the release of Debian GNU/Linux 5.0 alias “Lenny” the security support for the old distribution (5.0 alias “Lenny”) came to an end a few days ago. The Debian project is proud to have been able to support its old distribution for such a long time and even for one year after a new version has been released.
The Debian project released Debian GNU/Linux 6.0 alias “Squeeze” on
the 6th of February 2011. Users and distributors have been given a
one-year timeframe to upgrade their old installations to the current
stable release. Hence, the security support for the old release of 5.0
ended on the 6th of February 2012 as previously announced.
Previously announced security updates for the old release will continue
to be available on security.debian.org.
The Debian Security Team provides security updates for the current
the old distribution are also provided for one year after the new
distribution has been released or until the current distribution is
superseded, whatever happens first.
Upgrading to Debian 6.0 alias “Squeeze”
Upgrades to Debian GNU/Linux 6.0 from the previous release, Debian
GNU/Linux 5.0 alias “Lenny”, are automatically handled by the
aptitude package management tool for most configurations, and to a
certain degree also by the apt-get package management tool. As always,
Debian GNU/Linux systems can be upgraded painlessly, in place, without
any forced downtime, but it is strongly recommended to read therelease
notes for possible issues, and for detailed instructions on installing
Debian GNU/Linux is a free operating system, developed by more than
thousand volunteers from all over the world who collaborate via the
Internet. Debian’s dedication to Free Software, its non-profit nature,
and its open development model make it unique among GNU/Linux
The Debian project’s key strengths are its volunteer base, its
dedication to the Debian Social Contract, and its commitment to provide
the best operating system possible. Debian 6.0 is another important
step in that direction.
