Unable to create user group "Administrators"

Hello, have the following error when setting up Icinga Web 2; I’m using Ubuntu Server 20.04
FEHLER: Zend_Db_Statement_Exception in /usr/share/icingaweb2/library/vendor/Zend/Db/Statement/Pdo.php:225 with message: SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘icinga2.icingaweb_group’ doesn’t exist, query was: SELECT COUNT(*) AS cnt FROM icingaweb_group AS g WHERE (g.name = ‘Administratoren’)

I have no clue where to go from here.

Can you list your Icingaweb2 version as well as your Icingaweb2 installed modules?

It looks like you defined your icingaweb2 schema as icinga2. Did you run the SQL file to create those tables? There is a separate one for icingaweb2.

Thank you! I purged mysql before and forgot to add the icingaweb2 database again, now its working.
