I&#x27;ve had great success using Brightbox&#x27;s Ruby PPAs <a href="https:&#x2F;&#x2F;launchpad.net&#x2F;~brightbox&#x2F;+archive&#x2F;ubuntu&#x2F;ruby-ng" rel="nofollow">https:&#x2F;&#x2F;launchpad.net&#x2F;~brightbox&#x2F;+archive&#x2F;ubuntu&#x2F;ruby-ng</a>. Might want to give them a try first.
