¿Qué quisiera hacer al respecto? Sus opciones son:
Y o I : instalar la versión del desarrollador del paquete
N o O : conservar la versión que tiene instalada actualmente
D : mostrar las diferencias entre versiones
Z : ejecutar un intérprete de órdenes para examinar la situación
La acción por omisión es conservar la versión actual.
*** 10periodic (Y/I/N/O/D/Z) [por omisión=N] ? dpkg: error al procesar el
paquete update-notifier-common (--configure):
end of file on stdin at conffile prompt
This shows that you have modified a conffile on your system belonging to
this package, which means the package manager would have prompted you to
know what action to take with the conffile. However, because this was
part of an unattended upgrade, there was no possibility for you to
provide input, and the installation failed instead.
I'm not sure that this is the wrong behavior in such a case; doing
anything other than aborting the upgrade would mean taking action
without the user's input. In any case, if we are to do anything
different, it must be handled in the unattended-upgrades package, so
reassigning.
