Answer 2

I think your rvm is older version,

Install the latest (v1.25.25) rvm using:

$ \curl -L https://get.rvm.io | bash -s stable --ruby

then check the rubies available with this version:

$ rvm list known

then install the latest:

$ rvm install ruby-2.1.2

Note: Even if it does not show up in rvm list known it will try to download with the following message:

Installing Ruby from source to: /home/<YOUR_USER_NAME>/.rvm/rubies/ruby-2.1.2, this may take a while depending on your cpu(s)...

Answer 3

This error in my case was cased because apt-get update gave a n error. After doing and manual sudo apt-get update I notices that one of the repos gave an error "W: Failed to fetch". After editing the repo list and removing the one that gave the error I was able to install.

Answer 4

Try to use this for install latest ruby

rvm mount -r https://rvm.io/binaries/ubuntu/12.04/x86_64/ruby-1.9.3-p194.tar.bz2

for more help

rvm help mount

I tried most of above answers but none works for me, so i just change server If you are using rvm for ruby then this will work.

1. Goto directory etc/apt
2. click on Sources.list
3. Change the server to us or some else server
4. Reload (it will update your cache from that server)
5. Then run sudo apt-get update
6. Finally run rvm install 2.3.0
