Public bug reported:
When trying to upgrade from 18.04 to 20.04, I get the following error
"Impossible d'évaluer la mise à niveau
Un problème insoluble est survenu lors du calcul de la mise à niveau.
Cela a probablement été causé par :
* des paquets logiciels non officiels qui ne proviennent pas
d’Ubuntu.
Veuillez utiliser la commande « ppa-purge » du paquet
« ppa-purge » afin de supprimer les paquets d’un
dépôt PPA Launchpad, puis essayez de relancer la mise à niveau.
"
I tried the ppa purge but it does not solve the problem. I have tried with sudo
do-release-upgrade -d --allow-third-party and sudo do-release-upgrade -d but it
gives the same result
