Title:
  Error while updating ubuntu 18.04 to 20.04 on Zorin OS 15.3 x64

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  The error code(I am spanish so the messages are in this language):

  Calculando los cambios

  Calculando los cambios

  No se ha podido calcular la actualización

  Se produjo un problema irresoluble al calcular la actualización.

  Esto podría deberse a: 
  * Paquetes de software no oficiales, no proporcionados por Ubuntu 
  Utilice la herramienta «ppa-purge» desde el paquete 
  ppa-purge para quitar software de una PPA de Launchpad PPA e 
  intente actualizar de nuevo. 

  Si nada de esto es aplicable, entonces informe de este error usando 
  el comando «ubuntu-bug ubuntu-release-upgrader-core» en una terminal. 
  Si quiere investigar el problema por su cuenta, los registros en 
  «/var/log/dist-upgrade» contienen detalles de la actualización; en 
  particular, consulte «main.log» y «apt.log».
