The installation instructions for icinga2 recommend using icingadb
It’s recommended to use the newer Icinga DB feature, if you don’t need PostgreSQL.
It appears that icingaweb2 setup does not support icingadb. There is a step where the database backend is configured and only DB IDO is offered. Subsequently icingaweb2 shows errors about missing database tables.
I have reported this as github ticket #7934 which describes the full installation method used on a fresh install of Ubuntu 18.04.4. Can anyone here help me get this working? Has anyone got icinga2, icingaweb2 and icingadb working on Ubuntu? I am stuck and need this working to progress some urgent work.
