Title:
  Crash during update from ubuntu 18 to 20

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

Bug description:
  During the second step of upgrade named in french "Configuration des
  nouveaux dépôts logiciels", meaning config of new source lists
  repositories for softwares. I get this message asking me to check ppa-
  purge and contact the support :

  "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.

  Si rien de tout cela ne s'applique, signalez ce bogue à l'aide de la
  commande « ubuntu-bug ubuntu-release-upgrader-core » dans un terminal.
  Si vous souhaitez analyser le problème par vous-même, les fichiers
  journaux contenus dans le répertoire « /var/log/dist-upgrade »
  contiennent les informations sur la mise à niveau. Plus précisément,
  veuillez consulter les journaux « main.log » et « apt.log »."

  I checked the log and I found this :
