Icinga2 vSphere Modul Error

Hello everyone,

I'm currently trying to install Icinga2 with vSphere integration. Unfortunately, I keep encountering the same error. After creating the database and installing the necessary programs, an error message always appears when I try to configure vCenter:
Fatal error: Declaration of Evenement\EventEmitterTrait::on($event, callable $listener) must be compatible with ipl\Html\HtmlDocument::on($event, callable $listener): Icinga\Application\ClassLoader in/usr/share/icinga-php/vendor/vendor/evenement/evenement/src/EventEmitterTrait.phpon line28
I have do the Installation over the originel intruduction from icinga 2

https://icinga.com/docs/get-started/latest/
https://icinga.com/docs/icinga-vsphere-integration/latest/doc/01-Installation/

I hope you can help me

and in the mean time:

the vspheredb module still works with
icingaweb2 2.12.6
Icinga PHP Library 0.18.1
if you use icingadb-web you need v1.3.1 instead of 1.4.0

Thank you for your fast feedback. How do install with this version that you wrote? I got only error massages that cant find in the repo.

that depends on your distribution.
