Setting environment variables seem to be the solution:
But this is a problem which pops up regularily, so perhaps it is something more complex than just setting environment variables and depends on other things too. Just give it a try and report back.
In above thread this has worked:
You can add these lines to
~/.julia/config/startup.jl, which will execute on each new Julia session:ENV["HTTP_PROXY"] = "http://proxy.osmp.ru:3128" ENV["HTTPS_PROXY"] = "http://proxy.osmp.ru:3128"
