Can be, but honestly I do not remember to have installed any package from a previous version to Icinga2.

I've been reviewing this [1] documentation and see it mentions only the "conf.d" directory but not a directory tree. If I'm missing something, could you please tell me what part of the documentation do you mean?

Currently I was using these files in the "host" directory:

-------------------------------------------------------------------------------
root at icinga2:/etc/icinga2/conf.d/hosts# ll
total 20
-rw-r--r-- 1 root root   322 sep 18  2014 localhost.conf
-rw-r--r-- 1 root root 13657 mar 22  2015 local-network.conf
-------------------------------------------------------------------------------

Where local-network.conf has the definitions of the hosts and services to be monitored on the local network. Perhaps the suggestion is to move these files to the root of "conf.d" and delete the "hosts" directory?

After having removed the "localhost" directory I was able to make Icinga2 is up and running.

> Have a nice weekend,

Thank you. I hope you also had a good weekend :-)

Best regards,
Daniel
