[Bug 1909150] Re: can't upgrade OS

Reviewing the files from your upgrade attempt you seem to have enabled a
PPA that provides Xorg packages. This will prevent the upgrade as that
PPA contains package version numbers greater than the release to which
you are upgrading. You can revert the PPA by installing the ppa-purge
package from the official Ubuntu archive and then running 'sudo ppa-
purge ppa:oibaf/graphics-drivers'.  After that you can try upgrading
again and if it still fails open a new bug report.  Thanks and good
luck!

Title:
  can't upgrade OS

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

Bug description:
  ubuntu-bug ubuntu-release-upgrader-core

  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».
