Upgrade to Debian Squeeze

Debian 6.0 (Squeeze) is the current stable Debian release. As of 2013, all batch resources are running Squeeze exclusively. Desktop boxes should be upgraded asap.


Squeeze comes with KDE Version 4 instead of KDE 3. This brings a lot of changes and we are still struggeling to make the transition as smooth as possible.

Anyhow many parts of your KDE 3 settings will not be applicable any more or not properly converted and simply ignored. Some may also hinder the proper functioning of the KDE 4 version and have to be deleted.

We recommend at least 2 GB RAM for running KDE4. For older PCs with less RAM and no RAM extension possibilities we recommend using the alternative desktop environment XFCE that is also provided.

Printing Environment

Convenient printing to the old LprNG printserver (ie. kprinter) is no longer available in KDE 4. Use the new CUPS server instead, cf. PrintingHowtoCups .

dash vs. bash

The system /bin/sh is no longer linked to /bin/bash but to /bin/dash which is less heavyweight and promises faster shell invocations esp. on system bootup.

If your shell scripts make use of bash-specific shell (bashisms) code and do not have #!/bin/bash as their first line (aka. shebang) you will get syntax errors.

You can check for bashisms in your shell scripts with the checkbashisms utility.
