Your sources.list
is missing the main Debian repository. Add this line to /etc/apt/sources.list
and try installing rabbitmq-server
again:
deb http://ftp.us.debian.org/debian stable main contrib non-free
As you can see here, the rabbitmq-server
is indeed in the main debian repository, so after adding the line above you should be able to install it with
sudo apt-get install rabbitmq-server
Just make sure to choose a debian mirror that is close to you and edit the deb line accordingly.
