If your gem command is not current, you can update it like this:

<pre><code>gem update --system

To see if you can connect to rubygems.org using Ruby:

<pre><code>require 'net/http'
require 'uri'
puts Net::HTTP.get URI.parse('https://rubygems.org')
</code></pre>

If yes, that's good.

If no, then somehow Ruby is blocked from opening a net connection. Try these and see if any of them work:

<pre><code>curl https://rubygems.org

curl https://rubygems.org --local-port 1080

curl https://rubygems.org --local-port 8080

env | grep -i proxy

If you're using a company machine, or within a company firewall, or running your own firewall, you may need to use a proxy.

I have fixed this issue using the proxy command option of gem install. It has the following format:

Note, the IP address and the port number refers to a proxy. You should search for a proxy list and use one of the proxies there.

This is site with proxies: <a href="http://www.cybersyndrome.net/pla5.html">http://www.cybersyndrome.net/pla5.html</a>

Also, I have to try 7 or 8 different proxies in order to succeed. Do not give up.

I have tried most of the solutions suggested here but I had no luck.
I found a solution that worked for me, which was manually updating the gemfile to 2.6.7.
The guide on how to do is in guides.rubygems.org: <a href="http://guides.rubygems.org/ssl-certificate-update/#installing-using-update-packages" rel="nofollow noreferrer">installing-using-update-packages</a>

<blockquote>
 Download <a href="https://rubygems.org/downloads/rubygems-update-2.6.7.gem" rel="nofollow noreferrer">rubygems-update-2.6.7.gem</a> to your C:\
 
 Now, using your Command Prompt:
</blockquote>

<pre><code>C:\&gt;gem install --local C:\rubygems-update-2.6.7.gem
C:\&gt;update_rubygems --no-ri --no-rdoc 
</code></pre>

<blockquote>
 After this, gem --version should report the new update version (2.6.7).
 
 You can now safely uninstall rubygems-update gem:
</blockquote>

<pre><code>C:\&gt;gem uninstall rubygems-update -x
Removing update_rubygems
Successfully uninstalled rubygems-update-2.6.7
</code></pre>

The reason why this did not work before was because server used certificates SHA-1, now this was updated to SHA-2.

For what it is worth I came to this page because I had the same problem. I never got anywhere except some IMAP stuff that I don't understand. Then I remembered I had uninstalled privoxy on my ubuntu (because of some weird runtime error that mentioned 127.0.0.1:8118 when I used Daniel Kehoe's Rails template, <a href="https://github.com/RailsApps/rails3-application-templates" rel="nofollow">https://github.com/RailsApps/rails3-application-templates</a> [never discovered what it was]) and I hadn't changed my terminal to the state of no system wide proxy, under network proxy.

I know this may not be on-point but if I wound up here maybe other privoxy users can benefit too.

It is a permission issue.

I've been trying to install this 'rubygame' gem for some time, but whenever I use the command

<pre><code>gem install rubygame
</code></pre>

it will give an error:

<pre><code>ERROR: Could not find a valid gem 'rubygame' (&gt;= 0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
</code></pre>

I've also tried other gems but with similar results:

<pre><code>ERROR: Could not find a valid gem 'rake' (&gt;= 0) in any repository
ERROR: While executing gem ... (Gem::RemoteFetcher::FetchError)
Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
</code></pre>

I've already made sure I have an internet connection, and have already tried reinstalling both ruby and rubygems (currently using ruby 1.8, rubygems 1.7.2). Googling didn't help me at all. I would be very grateful if anyone can solve my problem. My sources list only shows <a href="http://rubygems.org">http://rubygems.org</a>

"Could not find a valid gem in any repository" (rubygame and others)
