les commandes setfacl/getfacl ne s'exécutant pas sur mon serveur, elles indiquent:
The program 'setfacl' is currently not installed. You can install it by typing:
Sudo apt-get install acl
quand j'ai essayé de l'installer, ça dit:
Sudo apt-get install acl
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package acl is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'acl' has no installation candidate
J'ai ajouté la ligne source suivante à la liste des sources de la configuration apt:
deb http://cz.archive.ubuntu.com/ubuntu trusty main
alors je peux installer acl normalement.
