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 Reference: The Debian Devel anounce
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 ;-)
