Ruby 1.9 and 1.8 on ubuntu 10.04
After asking a lot of people , and trying to go with the ubuntu way, a.k.a. synaptic I realized that the best way to install ruby on ubuntu is to avoid the ubuntu solution, it doesn’t get a lot of flexibility, and you may get in troubles when you want to do a strange thing.
So I advice you, to install RVM, and go this way, you will find a great tutorial on how to install it on ubuntu

also a great friend do a kick start tutorial on RVM here

Happy coding 
By the way, if you are trying this to install RoR3 be sure to install first the following gems rdoc , test-unit and rubytree or you will get errors like this:
ERROR: While executing gem … (Errno::ENOENT)
No such file or directory – lib
