You attempted to browse the contents of a virtual HTTP repository.
                  However, the intended way of use is the configuration of APT and
                  related package management systems to retrieve the software packages
                  through this service.
                  
To configure APT for use of Apt-Cacher NG you need to...  
                  
                  
                     - 
                     EITHER:  Configure APT to use a HTTP proxy by specifying
                     it in apt.conf or related configuration files, see
                     apt.conf manual page for details. Server and Port need to match
                     the values used to visit this page. For example,
                     edit /etc/apt/apt.conf (or create a new file called like /etc/apt/apt.conf.d/00aptproxy) and add the line:
                     
            Acquire::http::Proxy "http://${serverip}:${cfg:port}"; 
- 
                     OR:
                     Edit the /etc/apt/sources.list file and edit the source lines
                     therein, replacing the mirror hostname with the hostname of this
                     server machine and the port with ${cfg:port} (adding a port if none
                     specified). For example:
                     
                        deb http://ftp.debian.org/debian stable main contrib non-free
 deb-src http://ftp.debian.org/debian stable main contrib non-free
 deb https://get.docker.com/ubuntu docker main
 
 becomes:deb http://${serverip}:${cfg:port}/ftp.debian.org/debian stable main contrib non-free
 deb-src http://${serverip}:${cfg:port}/ftp.debian.org/debian stable main contrib non-free
 deb http://${serverip}:${cfg:port}/HTTPS///get.docker.com/ubuntu docker main
 Depending on the configuration, it might be possible to use a shortcut
                     for the base URLs without knowing the mirror, for example:deb http://${serverip}:${cfg:port}/debian stable main contrib non-free Ask your system administrator for details.
