do-release-upgrade crashed with FileNotFoundError in getListFromFile(): [Errno 2] El fitxer o directori no existeix: '/usr/share/ubuntu-release-upgrader/removal_blacklist.cfg'

[Walter Garcia-Fontes]

I got this error and the upgrade from Ubuntu 21.10 to 22.04 aborted with a black screen. I could recover from the boot recovery menu and the dpkg reconstruct option.
