Public bug reported:
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».

can't apply upgrade from 18.4 to 20.4, because there are unindentified
