I want to install a rails environment on Ubuntu 11.04. I tried:
$ sudo apt-get install ruby-rvm
But got the error:
Unable to locate package ruby-rvm
My other PC has Ubuntu 11.10, and this works fine there:
$ sudo apt-get install ruby-rvm
$ rvm install ruby-1.9.3-p125
$ sudo gem update --system
$ sudo gem install rails
