Thanks! So far the only strange thing from the logs is the GID set to 0. I guess you did not change manually the user's main group, did you?
Does the directory /home/invitado exist? What does running the command sudo /usr/sbin/adduser --gecos --disabled-password --home /home/invitado --gid 0 --shell /bin/bash --uid 1001 invitado say? If that fails, please also check that no group called 'invitado' or using GID 1001 exists, and try sudo addgroup --gid 1001 invitado sudo /usr/sbin/adduser --gecos --disabled-password --home /home/invitado --gid 1001 --shell /bin/bash --uid 1001 invitado -- [users-admin] Can't create new user accounts https://bugs.launchpad.net/bugs/459474 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-system-tools in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
