Failed update: "Your MySQL version does not meet the minimum requirement of 5.5.3."

The wizard is getting that attribute directly from the server via PHP’s PDO library. What or where are you looking to confirm that you are running MySQL Server 5.5.9?

Derek - thanks for responding.

I was going by what phpMyAdmin was telling me, but I confirmed via ssh:

mysql Ver 14.14 Distrib 5.5.59, for debian-linux-gnu (x86_64) using readline 6.2

Must be something with the PHP configuration then. Try this: download the Server Wizard and see what it provides for you. If it reports the same (it should), then add this at line 255 just before if ( ! $pdo):

var_dump($pdo->getAttribute(PDO::ATTR_SERVER_VERSION));exit;

And that should output the MySQL server version that PDO is configured to use.

Ah. Adding that line gave me this: string(15) “5.1.72-rel14.10”

Actually, upon a closer look, that matches the version of Percona Server. I’m not too familiar with that and how it compares to mysql, or what to do about it.

Percona is a drop-in replacement for MySQL, so you’d just need to update that package I suspect. I’d contact your server admin to request the update.
