RubyGems SSL Error

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

This error is actually produced by changes on rubygems site certificate in lieu of recent OpenSSL vulnerabilities. To fix this error one need to upgrade their rubygems

Specific problem with RubyGems

RubyGems bundles its trust certificate within itself (as it is used from command line tool), where some OS does not able to verify the identity of them.

Recently CA for RubyGems.Org has changed, thus changing the certificate. Because of this existing installation of rubygems has to be upgraded. In case of windows since most people use RailsInstaller it is still distributed with old rubygems.Leaving RubyGems 2.4 is broken on Windows.

Once official releases are out, installation might be simpler. In the meantime, please proceed using the instructions described below.

Installing using update packages
