For Windows Users  and maybe others   Rubygems org has a guide that not only explains how to fix this problem  but also why so many people are having it  SSL Certificate Update The reason for the problem is rubygems org switched to a more secure SSL certificate  SHA-2 which use 256bit encryption   The rubygems command line tool bundles the reference to the correct certificate  Therefore rubygems itself can   t be updated using an older version of rubygems  Rubygems must first be updated manually   First find out what rubygems you have   rubygems    v   Depending on whether you have a 1 8 x  2 0 x or 2 2 x  you will need to download an update gem  named    rubygems-update-X Y Z gem     where X Y Z is the version you need  Running 1 8 x  download  https   github com rubygems rubygems releases tag v1 8 30 Running 2 0 x  download  https   github com rubygems rubygems releases tag v2 0 15 Running 2 2 x  download  https   github com rubygems rubygems releases tag v2 2 3  Install update gem    gem install    -local full path to the gem file   Run update gem   update rubygems --no-ri --no-rdoc   Check that rubygems was updated   rubygems    v   Uninstall update gem   gem uninstall rubygems-update -x   At this point  you may be OK  But it is possible that you do not have the latest public key file for the new certificate  To do this   Download the latest certificate   currently AddTrustExternalCARoot-2048 pem  from https   rubygems org pages download  All of the certs are also located at   https   github com rubygems rubygems tree master lib rubygems ssl certs  Find out where to put it   gem which rubygems   Put this file in the    rubygems ssl certs    directory at this location   As per rubygems commit  the certificates are moved to more specific directories  Thus  currently the certificate AddTrustExternalCARoot-2048 pem  is expected to be on the following path lib rubygems ssl certs rubygems org AddTrustExternalCARoot-2048 pem

The particular case of RubyGems  the command line tool  is that it requires to bundle inside of its code the trust certificates  which allow RubyGems to establish a connection with the servers even when base operating system is unable to verify the identity of them   Up until a few months ago  this certificate was provided by one CA  but newer certificate is provided by a different one   Because of this  existing installations of RubyGems would have to been updated before the switch of the certificate and give enough time for the change to spread  and people to update   Anyone can find his solution by following the simple steps given in the link below  https   gist github com luislavena f064211759ee0f806c88

If you are using windows  open https   rubygems org  with internet explorer   Click on security information and import the certificate  The bottom line is your certification chain is outdated and you need to add this new certificate  Remember that this is not a security violation as long as you can validate the certificate as trusted

If you want to use the non-SSL source  try removing the HTTPS source first  and then adding the HTTP one   sudo gem sources -r https   rubygems org sudo gem sources -a http   rubygems org     UPDATE   As mpapis states  this should be used only as a temporary workaround  There could be some security concerns if you re accessing RubyGems through the non-SSL source   Once the workaround is not needed anymore  you should restore the SSL-source   sudo gem sources -r http   rubygems org sudo gem sources -a https   rubygems org

On Windows you ll have to use HTTP source to update gem then change back to using HTTPS    gem sources -r https   rubygems org  gem sources -a http   rubygems org  gem update --system gem sources -r http   rubygems org  gem sources -a https   rubygems org    Edit  Warning I m not sure if this is safe  Does anyone know if ruby packages are signed  The accepted answer looks like a better solution
