ERROR 2006 (HY000) at line 1: MySQL server has gone away

I am facing the same problem. I am trying to restore mysqldump file to my machine. The file have size of 2.7 MB

Answer 1

This usually means that you have "incompatibilities with the current version of MySQL Server", see mysql_upgrade. I ran into this same issue and simply had to run:

mysql_upgrade --password

The documentation states that, "mysql_upgrade should be executed each time you upgrade MySQL".
