Error while installing RVM on ubuntu 11.04. Seems to be git clone's error

When I try to install RVM the following error shows up:

$ bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
Cloning into rvm...
fatal: The remote end hung up unexpectedly
Cloning into rvm...
error: RPC failed; result=56, HTTP code = 100
fatal: The remote end hung up unexpectedly

ERROR: Unable to clone the RVM repository, attempted both git:// and https://

This is a git clone error I'm getting recently. e.g When I try to clone nodejs.

error: RPC failed; result=56, H开发者_JAVA百科TTP code = 100
fatal: The remote end hung up unexpectedly

What is the problem?

It would seem you're having some sort of network issue that is preventing you from retrieving the Git repository. The RVM script attempts to clone the repository first using git clone --depth 1 git://github.com/wayneeseguin/rvm.git, and if that fails, using git clone https://github.com/wayneeseguin/rvm.git. Git uses libcurl. The result=56 part of the RPC failed error is the libcurl error code; 56 means Failure with receiving network data.. The HTTP code = 100 part is the HTTP server status code that was returned to you; 100 means The client SHOULD continue with its request..

Your best bet is probably to start a network traffic sniffer (on Ubuntu, you can use Wireshark) to see exactly what packets are being transmitted/received on your workstation. Try installing RVM on different workstations in your network and on different networks. I did not have any issues on my machine.
