The Debian project is pleased to announce the second update of its stable distribution Debian GNU/Linux 4.0 (codename etch). This update mainly adds corrections for security problems to the stable release, along with a few adjustment to serious problems.
Please note that this update does not constitute a new version of Debian GNU/Linux 4.0 but only updates some of the packages included. There is no need to throw away 4.0 CDs or DVDs but only to update against ftp.debian.org after an installation, in order to incorporate those late changes.
New CD and DVD images containing updated packages and the regular installation media accompanied with the package archive respectively will be available soon at the regular locations.
Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at:
The installer has been updated to use and support the updated kernels included in this release. This change causes old netboot and floppy images to stop working; updated versions are available from the regular locations.
Other changes include stability improvements in specific situations, improved serial console support when configuring grub, and added support for SGI O2 machines with 300MHz RM5200SC (Nevada) CPUs (mips).
