Connection Timed out in Installing rails

Question

I am using Ubuntu 14.04 LTS and ruby version is: 1.9.3p484

While running the command

sudo gem install rails -v 3.2.18,

I am getting this error

WARNING:  Error fetching data: Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/specs.4.8.gz)
WARNING:  Error fetching data: Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
    Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/gems/activesupport-3.2.18.gem)

Now when I checked for

rvm requirements

I am getting the error: Segmentation fault(core dumped)

Answer 1

All those errors seem to come from connection attempts over HTTP, which is deprecated. In your Gemfile , the first line is probably

source :rubygems

you can try to change it to

source 'https://rubygems.org'

Answer 2

The Segmentation fault core dump error arises and it's a memory usage problem.This was not a rails problem. So need to format the system. Segmentation fault(core dump): This is the error which comes when a program try to use the same space which is already filled or try to use the space which is not present.

Thanks
