Public bug reported:

Prior filing this as potential bug help was sought but did not yield a
remedy

https://discuss.linuxcontainers.org/t/3-0-2-bug-cannot-create-root-
password-in-privileged-container/3425

host - ubuntu cosmic with 4.18.0-12 kernel / systemd 239-7 / apparmor
2.12

Whilst there is no issue with creating a root password via lxc-attach
and passwd in an unprivileged container it is however not possible to
create a password the same way for a privileged container (tried centos
7 and ubuntu cosmic).

Error reported from within the containers:

passwd: System error
passwd: Authentication token manipulation error

Error reported at the host:

passwd: PAM audit_log_acct_message() failed: Operation not permitted


Next tried with:

chroot /srv/lxc/container_name/rootfs passwd

but that produced the same error.


Next tried with:

lxc.cap.keep = CAP_AUDIT_WRITE

but the container would not boot.


Next tried with:

lxc.apparmor.profile = unconfined

but no remedy.


Next switched the kernel to 4.19.7 but no dice either.
