Linux mint won't turn on after a power outage. how to be?

Question

ubuntu

Hello, after a short power outage, linux mint does not log in as a user, it says that the session lasts less than 10 seconds, if you did not end the session yourself, this may mean that there is a problem in the installation or that there is not enough disk space... Try logging in into one of the failover sessions...
In the ~/.xsession-errors file it says that failed to connect virtualbox kernel service
X-session manager [2032]: critical: we failed,but the fail whale is dead. Sorry...
In principle, the number in brackets is always different...

Answer 1

the number in brackets is the process ID. log in as root and run the command skill -KILL -u твой-юзернейм
may help)
