问题
Here's the console output:
sergio@sergio-VirtualBox:~$ rvm list
rvm rubies
ruby-1.9.3 [ i386 ]
sergio@sergio-VirtualBox:~$ rvm use 1.9.3
Using /usr/share/ruby-rvm/gems/ruby-1.9.3
sergio@sergio-VirtualBox:~$ ruby -v
The program 'ruby' can be found in the following packages:
* ruby1.8
* ruby1.9.1
Try: sudo apt-get install <selected package>
So what's going on? Do I need to reboot my machine? Or should it work right off the bat? I'm using Ubuntu 11.10, any help is appreciated.

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:
sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh
open new terminal and validate environment is clean from old RVM settings (should be no output):
env | grep rvm
if there was output, try to open new terminal, if it does not help then restart your computer.
install RVM:
\curl -L https://get.rvm.io |
bash -s stable --ruby --autolibs=enable --auto-dotfiles
If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04, which gives a bit more explanation.

- Open Terminal.
- Go to Edit -> Profile Preferences.
- Select the Title & command Tab in the window opened.
- Mark the checkbox Run command as login shell.
- close the window and restart the Terminal.

I ran into a similar issue today - my ruby version didn't match my rvm installs.
> ruby -v
ruby 2.0.0p481
> rvm list
rvm rubies
ruby-2.1.2 [ x86_64 ]
=* ruby-2.2.1 [ x86_64 ]
ruby-2.2.3 [ x86_64 ]
Also, rvm current failed.
> rvm current
Warning! PATH is not properly set up, '/Users/randallreed/.rvm/gems/ruby-2.2.1/bin' is not at first place...
The error message recommended this useful command, which resolved the issue for me:
> rvm get stable --auto-dotfiles
