Hello to everyone.

it seems that ubuntu 20.10 does not like xen. During the the upgrade from focal fossa to groovy gorilla I have found this bug :


and after having installed a fresh copy of groovy gorilla,I found another bug,like this :


It's not freezing but holding, "Starting Hold until boot process finishes up ..." Because the dependencies are not started for the sssd.service, my computer is holding infinitely. System Security Services Daemon, I think this is apparmor,but I disabled and removed / purged it with all the dependencies,but the error persists. what can I do ?
