I'm facing these issue ( Oh no! Something has gone wrong. A problem has occurred and the system can't recover. Please contact a system administrator)

Yes. Its a new installation and after that I do “sudo apt update” next “sudo apt upgrade” . it need reboot than. And there was the problem.
Because of news installation, I’ve reinstall and do “sudo apt update” and do all installation (without "sudo apt upgrade). Roboot well and I can use it up to now.
