There's a simple command built-in that will pull it:
rvm implode
This will remove the rvm/ directory and all the rubies built within it. In order to remove the final trace of rvm, you need to remove the rvm gem, too, if you installed that:
gem uninstall rvm
There may be elements left over from a Homebrew, Apt or DNF install of it that require removal as well. This depends on how you installed it in the first place. That clean-up step is optional, as RVM will no longer be involved in Ruby, but can help keep things organized.
If you've made modifications to your PATH you might want to pull those, too. Check your .bashrc, .profile and .bash_profile files, among other things.
You may also have an /etc/rvmrc file, or one in your home directory ~/.rvmrc that may need to be removed as well.
Install RVM with RUBY
sudo apt-get install curl
after install
install rvm also ruby
\curl -sSL https://get.rvm.io | bash -s stable
if you face issue with the above line (Failed to connect to get.rvm.io port 443: Network is unreachable)
in browser go to https://get.rvm.io save the page in any location
make it executable file name rvm-installer
chmod +x rvm-installer
then do the following
bash rvm-installer stable --ruby
then check rvm list
note the version of ruby listing on terminal
**change terminal to login shell. open a new terminal **
then rvm use 2.1.1 => ( 2.1.1 version )
then its done!
pd@admin:~$ ruby -v
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-linux]
STEPS
1: go to [https://get.rvm.io][1] save the page in in home directory(filename rvm-installer)
2: chmod +x rvm-installer
3: bash rvm-installer stable --ruby
4:rvm use 2.1.1
5:gem install rails
programmers keep on coding with ruby.

It looks like a bug, but it most likely is fixed already as I can not reproduce it, update RVM and try again:
