Installation nuxeodrive sur Linux

Je suis les indications : https://github.com/nuxeo/nuxeo-drive/#ubuntudebian-and-other-linux-variants-client

Lorsque je ne mets pas de remarque c'est que tout se passe comme prévu

sudo mount -oremount,user_xattr /dev/sda3

comme easy_install n'est pas connue j'ajoute :

sudo apt-get install python-setuptools

sudo easy_install -U pip
sudo apt-get install python-pip python-dev python-qt4 libffi-dev

DRIVE_VERSION=release-2.0.1223 (je mets l'indice de version qui figure en haut de la page)
sudo pip install -U -r https://raw.github.com/nuxeo/nuxeo-drive/$DRIVE_VERSION/requirements.txt

provoque le warning : The directory '/home/francois/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Je relance avec le flag -H

sudo -H pip install -U -r https://raw.github.com/nuxeo/nuxeo-drive/$DRIVE_VERSION/requirements.txt

sudo -H pip install -U -r https://raw.github.com/nuxeo/nuxeo-drive/$DRIVE_VERSION/unix-requirements.txt
sudo -H pip install -U git+https://github.com/nuxeo/nuxeo-drive.git@$DRIVE_VERSION

Cannot find command 'git'

sudo apt-get install git-core
sudo -H pip install -U git+https://github.com/nuxeo/nuxeo-drive.git@$DRIVE_VERSION
