For me it was the apparmor profile acting up on me not allowing file locking the /etc/pwd.lock file:
operation="file_lock" pid=7432 parent=7431 profile="/usr/sbin/useradd" requested_mask="k::" denied_mask="k::" fsuid=0 ouid=0 name="/etc/.pwd.lock" Fixed it by unloading the profile: sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.useradd -- package usbmuxd 1.0.0-2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/521299 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
