Could not exec dpkg!
E: Sub-process /usr/bin/dpkg returned an error code (100)

It seems like an issue with dpkg, but shows a message that it's updated:

oot@gonzalo-Lenovo-G470:~# dpkg

No se ha encontrado la orden «dpkg», pero se puede instalar con:

apt install dpkg

any idea about how to fix it?
thanks in advance

This is a strange issue... This post may help.

thanks. I'll try this, then post informing

Unfortunatly it couldnt be done.
I need to install the ar command and it involves using dpkg, wich is the issue : couldnt exec dpkg

Anyone knows if is there another way to extract the dpkgdeb files obtained from ubuntu?

Really, dpkg should not fail... While a repair attempt might be worthwhile if it is easy... It is also concerning that it failed at all. I wonder what type of disk corruption would also be involved.
If it is feasible for you... I would recommend backing up personal files and Reinstalling Zorin OS fresh. It just seems a safer bet.

Yes, i completely agree .
Thanks anyway for your help.
