Hi Victor, you're just missing a Python module ("no module named gi.repository"). This has been encountered before, e.g. bug 1641423. No reason why it is sometimes missing has been found yet.
The module is provided by the python-gi package, which should have been installed as a dependency of the deja-dup-backend-gvfs package, which you have normally installed when you first opened Déjà-Dup's GUI (System Settings > Backups, a.k.a. deja-dup-preferences) and clicked the Install button at the bottom of the message informing you that additional packages were required. You did click that button, did you? Or was it not available? Can you also please report which packages are installed and which ones aren't, by running the following commands: apt-cache policy deja-dup-backend-gvfs apt-cache policy deja-dup-backend-cloudfiles apt-cache policy deja-dup-backend-s3 apt-cache policy duplicity apt-cache policy python-gi Look for the "Installed: (none)" and "Installed: <version number>" lines.
