I don't know why this error has occurred, but all I know is I have modified my sources list by adding "contrib" and "non-free" behind each "main"(s) and updated by "apt-get update" command a couple minutes ago.root@debian:~# apt-get install steam
Reading package lists... Done

Reading state information... Done
Package steam is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'steam' has no installation candidate
I am missing my strife so bad, so hopefully you guys can help.. I run debian stretch 64 bit, a stable release one under gnome's roof..
Thank you for further notices and guidance
