marketplace.key '""' is invalid

[jnweiger]

Seen in 10.13.3
The marketplace api key contains a literal pair of doublequotes. This prevents the market app to load anything. Instead, an error is shown.

/var/www/owncloud/config# grep -i market *
config.php:  'marketplace.key' => '""',

• change the field 'OwnCloud Markt API Schlüssel' from "" to empty string `` -> Änderungen Anwenden
• config.php still contains the invalid key.

Workaround:

• Change the field 'OwnCloud Markt API Schlüssel' from "" to empty string `` -> Änderungen Anwenden
• APP STOPPEN -> (wait ...) -> APP STARTEN
• then log in via ssh:

root@ucs-1114:~# univention-app shell owncloud occ config:system:set marketplace.key --value ''
System config value marketplace.key set to empty string

Now marketplace can be used.
