That's a very strange error. What versions of MediaWiki and Cargo are you running? And do you have MySQL installed on that server, and if so what version?

Product Version
MediaWiki 1.31.0-alpha
PHP 7.0.24 (fpm-fcgi)
MariaDB 10.0.32-MariaDB
ICU 56.1

Cargo = 1.7

I am running my server on a synology NAS. I tried using the default databases which is

$wgDBtype = "mysql";
$wgDBserver = "localhost:/run/mysqld/mysqld10.sock";
$wgDBname = "hurdwiki";
$wgDBuser = “XXX";
$wgDBpassword = “XXX";

I also tried with the following added to “LocalSettings.php"

$wgCargoDBtype = "mysql";
$wgCargoDBserver = "localhost";
$wgCargoDBname = "cargo";
$wgCargoDBuser = “XXX";
$wgCargoDBpassword = “XXX";

Very odd. If you uninstall Cargo, do you no longer see any errors when updating?

Looks like I’m getting the error when I remove Cargo as well.

Perhaps its another extension then.

Alright. Sounds like it might be core MediaWiki also...

most probably, mysql driver is not enabled.

Aklapper changed the task status from Open to Stalled.Apr 2 2018, 6:02 PM

Which distribution / operating system is this about? Which MySQL/MariaDB driver / package is installed?

See similar support topics like or .
Which makes me think that there is no software bug here.

@Mmiller0712: Could you answer my last question please? Thanks! :)
