W: You may want to run apt-get update to correct these problems The reason is, the host changed the IP to something else. I already changed /etc/apt/sources.list. However, I don't what to change so the error above won't show up. Thanks.
Okay, thanks.. I thought something still has to be changed since I already ran apt-get update several times before this error appeared.
Why did you change /etc/apt/sources.list? It has nothing to do with ISPConfig. It looks like you may have changed it to point to your own server which is wrong. It needs to point to the Debian repositories.
We are using repository cache server since we're hosting multiple Debian VPS (saving bandwidth). The repository cache server gets its update from the Debian repositories, all clients gets its update from the repo cache server.
