Mysql won't start after upgrading ubuntu from 18 to 20

This the error message I get when I tried to start mysql

Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.

I tried checking the mysql error log but it was empty, nothing came up.

I ran systemctl status mysql.service and this came up
