Using Github on Ubuntu

From Joomla! Documentation

If you encounter problems using GitHub on an Ubuntu system these hints may help you.

Typical symptoms include Eclipse failing with unknown exceptions and this sort of thing on the command line:

error: RPC failed; result=56, HTTP code = 200
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed

Upgrade to the latest version of Git

GitHub oftens seems to use a version of git that is higher than the version distributed in the current LTS version of Ubuntu and this can cause problems if the git protocol has changed. At the time of writing the current Ubuntu LTS is 12.04 which ships with git version 1.7.8, but GitHub requires 1.7.10 minimum. (See [1] for the latest version requirements). To upgrade git you need to add git's package repository to the package manager then upgrade. This used to be easy until Unity came along, so now you have to open a terminal window and enter the following commands:-

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get upgrade

(you will be prompted for your password when you enter the first line).

Use the git: protocol specifier

When cloning a repository on GitHub you would normally copy the repository name given which has either an https: or an ssh: protocol specifier. For some reason these don't work and the solution is to manually change the protocol to git:. For example, the repository URI for the Joomla CMS should be, so try using git:// instead.
