Check that there is not a proxy in the cluster. In that case, you should have to configurate github for allowing to download, see:

Cross-compilation succeeds and julia repl runs, as long as there is no need to load dependencies (e.g. MPI) at run-time. We are able to run git and curl from command line on these systems, but julia appears to be installing it’s own versions of these, and they are unable to navigate the proxy; support is explicitly disabled in curl. The error returned in the repl is: (v1.0) pkg\> add MPI C…

Has the cluster access to internet? If not, that could have a more difficult solution.
