Why can't I set the default Ruby version in Ubuntu?

Solution 1
Normally under Ubuntu you need to do:
sudo update-alternatives --config ruby
That will allow you to set the default to any available version of ruby installed on your system. This is easily installed from repositories.
Solution 2
I would avoid setting particular version to default, better to use .rvmrc files with gemset and ruby version per project.
RVM way should be:
rvm 1.9.2-p180 --default
rvm use default
Also, I guess you might better to switch to 1.9.3. It is quite easy to do with rvm:
rvm install 1.9.3
- RVM way will allow you to follow same approach on different platforms (Mac for example)

I'm trying to set my Ruby version to be 1.9.2, but I can't change it from the system Ruby installation. What am I doing wrong?
My terminal output is:
$ rvm list rvm rubies => ruby-1.9.2-p180 [ i386 ] $ rvm use default Using /usr/share/ruby-rvm/gems/ruby-1.9.2-p180 $ ruby -v ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]
