Debian 8 Jessie sources.list, missing installation sources.


Each time I install Debian Jessie or Debian 8 I notice that I can not install any software packages afterwards. I’m not sure if it is me, or the installation media, but the sources.list is missing entries. Recently I tried installing xrdp, which allows Windows OS machines to RDP into Linux OS machines.

Commands such as…

apt-get update
apt-get upgrade
apt-get install package_name

… yielded no results. When I navigate to /etc/apt/sources.list I noticed there were only 3 entries in the file.

deb cdrom:[Debian GNU/Linux....

deb jessie/updates main contrib
deb-src jessie/updates main contrib

However the Debian Wiki specifies two additional sources.

deb jessie main
deb-src jessie main

deb jessie-updates main
deb-src jessie-updates main

Once you add these to your sources list and run the above commands the
packages should update, and you can proceed with installing XRDP.
