[RESOLU] Duplicity et paramiko : droits

Bonsoir à tous,

je viens de monter un VPS chez un hébergeur.

J'ai installé duplicity

sudo apt install duplicity

et paramiko

sudo apt install python-pip
sudo pip install paramiko

J'ai fait un script qui engage duplicity à faire une sauvegarde et à l'envoyer sur un serveur distant.
Je l'ai placé dans /home/user2/
Je peux lancer le script avec

sudo ./monscript.sh

Mais si je le lance en tant que simple user2, j'obtiens :

Comment peut-on expliquer que duplicity ne fonctionne que pour root ?

J'ai besoin de le lancer par user2, car c'est user2 qui a la clé ssh pour se connecter au serveur automatiquement, ubuntu (root) se fait jeter tout naturellement:

Re : [RESOLU] Duplicity et paramiko : droits

C'est probablement dû au fait que tu as installé paramiko avec sudo pip, au lieu de pip.
Je connais une bonne manière de ne pas avoir de problème avec pip : ne pas l'utiliser
Il existe des paquets python-paramiko et python3-paramiko dans les dépôts, installe plutôt ça avec apt, tu auras probablement moins de problèmes… (en ayant d'abord désinstallé la version que tu as installée via pip)
