I'm quite new to Raspberry Pi and Linux/Debian, so please bear with me. I have been trying for hours now to install rabbitMQ on my Raspberry Pi 3, to no avail. I followed the steps, but in the end I just get this whenever I try to write sudo apt-get install rabbitmq-server :

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

After seeing this, I realize that my Erlang wasn't the correct version, and needs to be 1:21.3, instead of 1:21.2, so I went to go and update it, but it then says:

pi@raspberrypi:~ $ sudo apt-get install erlang
Reading package lists... Done

erlang is already the newest version (1:21.2.6+dfsg-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I looked on the Erlang web site and it just says write apt-get install erlang to make it work, but for some reason it just wants to stay at version 1:21.2.6, instead of the 22.2 that seems to be a latest version. Does anyone have any advice?
