Unable to install rubygems through rvm

Question

I'm a noob in ruby and i'm trying to setup Ruby on Rails on ubuntu 12.04. I'm following steps as given in this site https://www.digitalocean.com/community/articles/how-to-install-ruby-on-rails-on-ubuntu-12-04-lts-precise-pangolin-with-rvm

But whenever i try to run this command > rvm rubygems current i get an error

"Retrieving rubygems- There is no checksum for 'http://production.cf.rubygems.org/rubygems/rubygems-.tgz' or 'rubygems-.tgz', it's not possible to validate it. If you wish to continue with unverified download add '--verify-downloads 1' after the command."

Any help on this on how to proceed.

Answer 1

It looks like a bug, but it most likely is fixed already as I can not reproduce it, update RVM and try again:

rvm get stable
rvm rubygems current
