This is the Debian package repository of <%= @origin %>. It is used for internal distribution of locally built packages not yet part of Debian. Feel free to use it for yourself, but it comes at no warranty.
In your /etc/apt/source.list:
deb http://debian.<%= @domain %>/debian stable main deb-src http://debian.<%= @domain %>/debian stable main
stable can be replaced by testing
or unstable if you wish to test the development version
of packages.
This archive self-signs packages uploaded to it (and packages uploaded are verified against a whitelist of trusted uploaders) using OpenPGP (GnuPG, to be more precise).
The key of the archive is in the key.asc file. You should add the key using something like this:
wget http://debian.<%= @domain %>/debian/key.asc apt-key add key.asc apt-get update
