Curl returns Error status 22 when installing rvm from get.rvm.io

Question

I was trying to install Ruby on Rails using RVM. As the first step, I had to download rvm and used the following code.

curl -L get.rvm.io | bash -s stable

It seems like curl have successfully downloaded the file from get.rvm.io and called bash to run it. The downloaded script is attempting to download rvm installation file but fails with following error.

Could not download 'https://github.com/wayneeseguin/rvm/archive/stable.tar.gz'.
curl returned status '22'.

All the answers given at https://stackoverflow.com/questions/15730689/cant-install-rvm-on-linux-mint-14 and Error installing rvm (Ruby version Manager)

are tried but failed to resolve the problem.

Is there any method to resolve this problem or an alternate way to install latest version of Ruby and Ruby on Rails (with or without using rvm).

I was able to reproduce the error on two different PCs on two different networks with Linux Mint 12 and Linux mint 14.

Here is the command-line output shown:

curl -L get.rvm.io | bash -s stable

Answer 1

GitHub experinced a DoS attack today ( https://status.github.com/messages ):

GitHub.com is undergoing a series of DoS attacks. We're temporarily degrading several of our services as we continue to fight off these attacks.

Probably you need to try once more.

Answer 2

try with:

curl -L get.rvm.io | bash -s head

there are no big changes on master compared to stable and everything should be just fine
