[Bug 684367] Re: package bind9 1:9.7.0.dfsg.P1-1ubuntu0.1 failed to install/upgrade: el subproceso script post-installation instalado devolvió el código de salida de error 1

Hello Gustavo, thank you for taking the time to file this bug report and
help us make Ubuntu better.

This seems to be the cause of the problem:

Añadiendo el usuario del sistema «bind» (UID 116) ...
Añadiendo un nuevo usuario «bind» (UID 116) con grupo «bind» ...
useradd: no se puede bloquear /etc/passwd; inténtelo más tarde.
adduser: `/usr/sbin/useradd -d /var/cache/bind -g bind -s /bin/false -u 116 bind' devolvió el código de error 1. Saliendo.
dpkg: error al procesar bind9 (--configure):
 el subproceso script post-installation instalado devolvió el código de salida de error 1
Configurando pdns-recursor (3.1.7.2-1) ...

My spanish is rusty, but I believe that means that it could not lock
/etc/passwd.

Can you try running

sudo dpkg-configure -a

And see if that completes this configuration step? If not, you may want
to run

sudo fuser -v /etc/passwd

and see what process has /etc/passwd locked, and finish/kill that
process, then try again.

Marking Invalid, as this appears to just be a temporary lock problem and
not a bug.

** Changed in: bind9 (Ubuntu)
       Status: New => Invalid
