On my Linux system Ubuntu 14.04.2, When I run gem update, I got this:
Updating installed gems
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ECONNREFUSED: Connection refused - connect(2) for "s3.amazonaws.com" port 443 (https://api.rubygems.org/specs.4.8.gz)
And When I run gem update --system, I got this:
Updating rubygems-update
ERROR: While executing gem ... (Gem::SpecificGemNotFoundException)
Could not find a valid gem 'rubygems-update' (= 2.4.8) locally or in a repository
How do I resolve this problem?
