    You probably noticed by now, that Debian GNU/Linux 5.0 aka "Lenny" hasn't been released in September. The reason: too many bugs need to be fixed.

    When Lenny has been released, you can upgrade from Etch to Lenny according the steps below:
    (According the official Debian documentation, these 5 steps describe the safest way to do that job).

    STEP 1:
    -------
    Make a backup of your current Debian Etch system.

    STEP 2:
    -------
    Change the content of the file /etc/apt/sources.list.
    This means that you need to change "etch" into "lenny".
    So in my case i have to change:

    deb http://ftp.nl.debian.org/debian/ etch main
    deb-src http://ftp.nl.debian.org/debian/ etch main

    deb http://security.debian.org/ etch/updates main contrib
    deb-src http://security.debian.org/ etch/updates main contrib

    into:

    deb http://ftp.nl.debian.org/debian/ lenny main
    deb-src http://ftp.nl.debian.org/debian/ lenny main

    deb http://security.debian.org/ lenny/updates main contrib
    deb-src http://security.debian.org/ lenny/updates main contrib


    Beware:
    if you use "stable" instead of "etch", your system will make use of the packages provided by Debian Lenny from the moment on that Lenny gets stable!


    STEP 3:
    -------
    Execute the command: aptitude update
    to get information about new packages

    STEP 4:
    -------
    Execute the command: aptitude install dpkg aptitude apt
    to install the newest package management

    STEP 5:
    -------
    Execute the command: aptitude full-upgrade

    Confirmation

    I tested this method on my testing server with Debian Etch and ISPConfig 3.0.0.7.
    The upgrade to Debian Lenny was succesful. :)
    Don't perform this upgrade on a production server until Lenny is stable.
    It seams that ISPConfig 3 runs fine on Lenny.

    Hans, how do I make sure I update etch instead of stable?

    Never mind, I found it:

    /etc/apt/sources.list should have (or another server if you're not near Essen)

    ----------------------

    deb http://debian.uni-essen.de/debian/ etch main non-free contrib

    deb http://security.debian.org/ etch/updates main contrib non-free

    ----------------------

    Actually, when Lenny goes stable, it would be a good idea to put a "heads up" notice in the forums before noobs like me destroy their servers ;-)
