What really causes PHP MySQL library version differs from your MySQL server version?

Question

This message appears in PhpMyAdmin. Often after some update.

There are already a lot of similar questions. One typical answer is "update your libs". But in the end I still see a lot of people who can't solve it. (myself included)

I've tried to reinstall everything from scratch but it's still there and I get this exact version error:

Your PHP MySQL library version 5.5.34 differs from your MySQL server version 5.1.69.

I've added the output of my packages list. Everything looks correct. Or so I think. I don't understand where this 5.1.69 version comes from. I don't have much knowledge of linux / server setup.

Is there any linux/server wizard who can help? thank you : )

Solution

Your php-mysql package has been linked against an older MySQL client library. It's strongly suggested to install php-mysqlnd, see http://www.webtatic.com/packages/php54/. Then restart your web server.
