can't get it to run

[m-arx]

my create command:

sudo docker create
--name=cups
--restart=always
--net=host
--privileged
-v /volume1/docker/AirPrint/config:/config
-v /etc/avahi/services:/services
-e CUPSADMIN="leprint"
-e CUPSPASSWORD="HellFire123!"
quadportnick/cups-airprint

logs has a loop of:

• grep -ci leprint /etc/shadow
• [ 0 -eq 0 ]
• useradd -r -G lpadmin -M leprint
• echo leprint:HellFire123!
• chpasswd chpasswd: (user leprint) pam_chauthtok() failed, error: System error chpasswd: (line 1, user leprint) password not changed

I have also tried admin:password, cupsadmin:cupspass - always this loop.

what's wrong?

I cannot reproduce this error on my system (Ubuntu 20.04, Docker version 20.10.2, build 2291f61).

I would recomment that you switch to one of the many forks, cause this repository seems to be unmaintained (last commit four years ago) and uses an outdated base os (Ubuntu 17.04) which is unsupported fo three years.
My recommendation would be @chuckcharlie's fork.
