How to Install Icinga 2 Monitoring Software on Debian 12

Caution

Fix admin email in /etc/icinga2/conf.d/users.conf prior to starting **any** Icinga related service:

object User "icingaadmin" {
  import "generic-user"

  display_name = "Icinga 2 Admin"
  groups = [ "icingaadmins" ]

  email = "root@localhost"
}

object User "icingaadmin" {
  import "generic-user"

  display_name = "Icinga 2 Admin"
  groups = [ "icingaadmins" ]

  email = "yourEmail@whatsoever.org"
}

Timezone considerations.
