# ! [rejected]        master -> master (fetch first)

#error: failed to push some refs to '/home/charles/serverTestGit/projet.git/'

#hint: Updates were rejected because the remote contains work that you do

#hint: not have locally. This is usually caused by another repository pushing

#hint: to the same ref. You may want to first integrate the remote changes

#hint: (e.g., 'git pull ...') before pushing again.

#hint: See the 'Note about fast-forwards' in 'git push --help' for details.
