Phpmyadmin broken - version issue


More of a copy and paste of a response.

On a fresh install of ee (2.2.2) phpmyadmin is throwing up a bunch of errors and eventually after logging in I get the infamous :

“Your PHP MySQL library version 5.5.40 differs from your MySQL server version 5.6.21. This may cause unpredictable behavior.”

Appears to be related to an update to Percona 5.6.21 which I should’ve paid more attention to. The package mysql-common is the issue. It’s held at 5.5.40 and I’m not able to figure out a way of updating it cleanly.

I realise this isn’t strictly an EE issue but I suspect a bunch of people may be hitting this issue soon as they upgade to 5.6.21 of Percona.

Is there a nice way of fixing this?

Appreciate any help.

There’s no opportunity to upgrade the client lib unless I’m missing a PPA somewhere.
