Mysql won't start after upgrade

Hello,

after the last Mysql update, my Mysql Installation won’t start:

[root@nuc ~]# systemctl start mysqld
Job for mysqld.service failed because the control process exited with error code.
See "systemctl status mysqld.service" and "journalctl -xe" for details.

[root@nuc ~]# journalctl -xe

This is the output from mysqld.log:

Has anybody an idea what the problem is?

Thanks for your support!

Sorry, my post was to early. Found the solution in the Mysql Forum:
https://forums.mysql.com/read.php?11,674428,674428

The solution is:

chown mysql:mysql /var/lib/mysql/mysql_upgrade_info

@ankosu welcome to the forum! Thanks for the solution. I’ve marked it as so now. (Everyone can when they’ve gained enough trust levels)
