I am using: Ubuntu 20.04
Icinga Version: r2.13.5-1
At stage: Monitoring Backend we are offered “Backend Type” of IDO only.
I have the option to choose “MySQL”, but I still get the error: Cannot find the IDO schema. Please verify that the given database contains the schema and that the configured user has access to it
If I skip validation, when I login to Icinga2 I get database error on the right, as mentioned on the Github issue.
At the beginning of the installation wizard for Icinga Web 2, make sure that the Icinga DB Module is enabled. If it doesn’t show up, please have a look at Ubuntu - Icinga DB Web
I managed to install it. I needed to not enable the IDO module during configuration if Icinga Web (I made the mistake to have it together with Icinga Web).
