Install ruby-rvm on Ubuntu 11.10 with ruby 1.9.3

Question

rvm installs properly through: sudo apt-get install ruby-rvm

When I try to install ruby 1.9.3 I get these errors?

anthony@SnakeDoc:~$ rvm install 1.9.3

I tried to chmod the directories where I get access denied but it does not fix the problem. Any suggestions?
