<div>Installing RDoc documentation for bundler-1.3.5...</div></div><div>---</div><div><br></div><div>Any thoughts?! Apparently, the package didn't goes back to the Instance... But I don't know how to fix it... =P</div>
<div><br></div><div>I tried a lots of variants of this setup (playing with quantum networks, routers and Floating IPs) but, no success... I can't run "gem install bundler" form within any Instance... But I can navigate, use apt-get update and etc... :-/</div>
<div><br></div><div>NOTE: I noted that the rubygems is hosted at the AWS + CloudFront, and, the IP of it keep changing... It differs a bit from this mail and pastebin that I posted.</div><div><br></div><div>NOTE 2: The ubu-1 have no Floating IP attached to it, I'm trying to run "gem install bundler" from VNC console after changing "ubuntu" user password... Everything here is based on Ubuntu 12.04.2 + Grizzly from UCA, including Instances (ubu-1) and servers (network, controller, node, etc)...</div>
