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 :

https://bugs.launchpad.net/ubuntu/+s...t/+bug/1901398

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

https://ibb.co/vHxsffZ

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 ?
