package cron 3.0pl1-124ubuntu2 failed to install/upgrade: el subproceso instalado el script post-installation devolvió el código de salida de error 1

[juan]

Hi, I'm doing this experiment to my ubuntu installation

i had 14.10 installed and i downgraded to 14.04LTS in order to get the
long term support, as 1410 was not maintained anymore.

So I changed the utopic for trusty in all de deb lines in etc/apt/sources.list

Now
i am trying now to install a new ppa to get webmin

but before i updated/upgraded and there i got
lots of errors. when trying to desactualize a lot of packages

but the worse of them ,i believe, is that cron and initscripts packages cannot be upgraded.

I'm open to all the questions and testing you would propose.

Have a nice time

Kindly, Juan.
