I try to initialise icingaweb2 and therefore, the follwoing command prerequisite to the installation/configuration of the webinterface fails:


[...]

ERROR: Icinga\Exception\IcingaException in /usr/local/www/icingaweb2/library/Icinga/Cli/Command.php:130 with message: Can't change the group of /usr/local/etc/icinga2web to www: chgrp(): Unable to find gid for www


I consider this a newly introduced bug since I had already installed the port net-mgmt/icingaweb2 on that sepcific server. The group 'www' is also present on that system.

The error above is suggested to be fixed by recompiling php56-xxx ports, so I did recompilation/reinstallation all of them including these ports, no matter whether they are requisite or not to the port:
