Hi Falko! In your tutorial your forgot to tell how to get receive and install the key for the repository. Without the key you'll receive an error when executing "apt-get update". Adding the key is done with these two commands: Code: gpg --keyserver pgp.mit.edu --recv-keys C514AF8E4BA401C3 gpg --armor --export C514AF8E4BA401C3 | apt-key add - Unfortunately even then I receive these mesages when attempting "apt-get update": Code: W: Conflicting distribution: http://etc.inittab.org etch/ Release (expected etch but got ) W: Probieren Sie »apt-get update«, um diese Probleme zu korrigieren. I'm using a fresh clean Debian Etch (64 bit) with the perfect setup applied and ISPConfig installed. Any suggestions?
