Hi there @raulwassermann,

Would you mind sharing how did you install PHPmyAdmin exactly?

What I could suggest in this case is either installing PHPmyAdmin manually, to do that you can follow the steps here:

Or rather than using PHPmyAdmin, I would recommend using an SQL client installed directly on your laptop and then use SSH tunnel to connect to your MySQL database.

You can take a look at this tutorial here on how to do that with Workbench:

Hope that this helps!
Regards,
Bobby
