1. Installing the Gem packages Jekyll:

   gem install jekyll
   

What does this error mean?

• This error means that there was a timeout while trying to reach the rubygems server.

Why did this error occur?

• api.rubygems.org is currently experiencing issues with IPv6 setup: this hostname has 4 IPv6 addresses, but responds on neither of them.
• Neither to ping, nor to TCP connection attempts. When you are running gem, your gem tries IPv6 addresses first and times out on them, not having time to even try IPv4 addresses.

Solution

• The solution is to lower priority of IPv6 addresses for api.rubygems.org, so that gem will try IPv4 addresses first.
• In order to do it, put these lines into /etc/gai.conf
