package model-builder 0.4.1-4ubuntu1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 1

[Juan Carlos Chavarria]

Binary package hint: model-builder

These package calls an older python version (2.6) but it needs at least 2.8 version of python. When I changed python configuration i had several problems so I return to the previous one, that's why model builder crashes. I read several forums and it seems to be no satisfactory answer...

Greetings,
