I have a strange problem with git. When I try to clone a repository (I tried with severals) the terminal outputs:
ma7730@debian:$ git clone https://github.com/qgis/QGIS-Documentation.git
Cloning into 'QGIS-Documentation'...
fatal: unable to access 'https://github.com/qgis/QGIS-Documentation.git/': GnuTLS recv error (-54): Error in the pull function.
Using git 2.1.0 on a debian testing (jessie) machine.
I don't know what should I do to fix this problem, somebody has an idea?
