I am unable to clone the uefi-tools git using "git clone git://git.linaro.org/uefi/uefi-tools.git". I get this output Cloning into 'uefi-tools'... fatal: unable to connect to git.linaro.org: git.linaro.org[0: 54.247.55.40]: errno=Connection timed out maybe the GIT moved, or I have some permission issues ?
