New user creation Error: Password not accepted due to PAM restrictions

After the latest updates I am unable to create new users due to an error generated by PAM restrictions.

Error: Password not accepted due to PAM restrictions!


OS Debian GNU/Linux 10 (buster)

Changing password seem to fail? Did you modify the minium password requirements in /etc/

See for more info:

Adding parameters in /etc/pam.d/common-password does not solve the problem, it is not possible to create a new user.

password requisite retry=3 minlen=8 enforce_for_root difok=3 dictpath=/usr/share/dict/common enforce_for_root password [success=1 default=ignore] obscure use_authtok try_first_pass sha512

No it will make even worse…

What happens if change it to:

# /etc/pam.d/common-password - password-related modules common to all services
# This file is included from other service-specific PAM config files,
# and should contain a list of modules that define the services to be
# used to change user passwords. The default is pam_unix.
# Explanation of pam_unix options:
# The "sha512" option enables salted SHA512 passwords. Without this option,
# the default is Unix crypt. Prior releases used the option "md5".
# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
# login.defs.
# See the pam_unix manpage for other options.
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
password [success=1 default=ignore] obscure sha512
# here's the fallback if no module succeeds
password requisite
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
password required
# and here are more per-package modules (the "Additional" block)
# end of pam-auth-update config
