There seems to be a bunch of people experiencing problems updating from v.95 of Ruby Gems to the latest greatest version. Here's how I did it in two easy steps:

sudo gem install rubygems-update
sudo update_rubygems

Worked like a charm for me on Sidux and I'm sure it'll go over smoothly on Ubuntu as well. Just for kicks run gem -v after you're done and make sure the output is something later than 1.0.1.

Once you've got the latest gems installed, make sure you run sudo gem update to get everything else up to speed.
