| ## 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](http://railsinstaller.org) 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 | |
| 1.) Find RubyGems version by running `gem -v` | |
| 2.) Download `rubygems-update-X.Y.Z.gem` (find the version higher than your current version) | |
| You can find download links at GitHub under | |
| [Releases](https://github.com/rubygems/rubygems/releases). | |
| version for the version of RubyGems you need to update: | |
| - Running 1.8.x: download [1.8.30](https://github.com/rubygems/rubygems/releases/tag/v1.8.30) | |
| - Running 2.0.x: donwload [2.0.15](https://github.com/rubygems/rubygems/releases/tag/v2.0.15) | |
| - Running 2.2.x: download [2.2.3](https://github.com/rubygems/rubygems/releases/tag/v2.2.3) | |
| Please move file out of Downloads/ folder to somewhere you can later point out | |
| 3.) Install gem locally (by running below specified command) | |
| ``` | |
| C:\> gem install --local C:\rubygems-update-1.8.30.gem | |
| C:\> update_rubygems --no-ri --no-rdoc | |
| ``` | |
| 4.) After this check gems version `gem -v`. This should be updated version | |
| 5.) You could now uninstall `rubygems-update` | |
