I am trying to setup a cluster with 2 computers for the first time. I have searched for tutorials for how to do it on linux mint, but the only tutorials I can find are for redhat instead of mint. I meet my first road block when trying to follow this tutorial when using 'yum'. I don't believe you can, or should use yum on linux. The packages I am trying to install is "ricci","luci","ccs", and "cman", all of which are not in the linux mint 20.1 repository. I am wondering if and how you can access other linux repositories. I am aware that you can download things from gitgub using the command "git clone". Any knowledge will be helpful!
