Hi, Do you have steps to reproduce this please? What makes you think it is a bug in the packaging as opposed to a configuration problem on your system?

IIRC it is a conffile shipped by mysql-server-5.6. > 2015-11-22 21:53:53 4936 [ERROR] Fatal error: Can't open and lock > privilege tables: Table 'mysql.user' doesn't exist This I have seen. I think upstream know more about it, but I don't recall the details. Have you ever installed MariaDB? Because the migration path from MySQL back to MariaDB isn't automatic. > Severity: critical > Justification: causes serious data loss I don't think this is justified until we can determine that this is really a bug. For that we need steps to reproduce please. You said that you found this on a test server. Can you restore the test server to find out what the state of the system was before you attempted the upgrade? Thanks, Robie
