package ruby-rvm 1.6.9-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[Mike Hayes]

This is a clean install of 12.04. iso was downloaded today, 1st May 2012. After install, the update manager ran to update some mozilla and other packages. A restart was required at this point.

Once the system came back up, I apt-get installed curl and then did sudo apt-get install rvm
It downloaded and installed all dependecies after that and failed at the end with the error :
