When trying to install the ejabberd server from the Apps page I get the following error
"Error installing application: Error during installation E: The repository ‘Index of /debian-security stable/updates Release’ no longer has a Release file. "
What does your /etc/apt/sources.list file contain?
I remember seeing an error like this, then I changed /etc/apt/sources.list to
deb http://deb.debian.org/debian stable main
deb-src http://deb.debian.org/debian stable main
deb http://deb.debian.org/debian stable-updates main
deb-src http://deb.debian.org/debian stable-updates main
deb http://security.debian.org/debian-security/ stable-security main
deb-src http://security.debian.org/debian-security/ stable-security main
