Error while upgrading to 16.04: 'LC_CTYPE=fr_FR.UTF-8' is not a git command and many dependency errors

I just upgraded to 16.04 using sudo do-release-upgrade.

I saw this message at the end of the process :

The upgrade has completed but there were errors during the upgrade process.

Now if I do: $ sudo apt full-upgrade I get this log:
