Can't complete horde webmail-install script

[Wojciech Myszka]

After running webmail-install I expected basic configuration and system ready for run and further configuration

After fresh system installation, invoking webmail-install script choosing: mysql, unix socket, no ssl, empty certification authority and disabled split reads script writes main configuration file

Writing main configuration file... done.

creates and updates database tables

Creating and updating database tables... done.

and stops with an error:

PHP Fatal error: Uncaught TypeError: Argument 1 passed to IMP_Application::exceptionHandler() must be an instance of Exception, instance of ParseError given in /usr/share/horde/imp/lib/Application.php:610
Stack trace:
#0 [internal function]: IMP_Application->exceptionHandler(Object(ParseError))
#1 {main}
  thrown in /usr/share/horde/imp/lib/Application.php on line 610

this message is repeated three times (and appears as a broadcast message from systemd-journal).

All configuration files (conf.php) are created.

Can not connect to site (there is an error: The server encountered an internal error or misconfiguration and was unable to complete your request.) and in apache log file: /usr/share/horde/.htaccess: Require not allowed here.

After commenting this line Require all granted (module authz_core loaded) I can connect to administrative interface of horde and can enter for configuration all applications but horde.
After entering horde configuration there is the same message:

Uncaught TypeError: Argument 1 passed to IMP_Application::exceptionHandler() must be an instance of Exception, instance of ParseError given in /usr/share/horde/imp/lib/Application.php:610 Stack trace: #0 [internal function]: IMP_Application->exceptionHandler(Object(ParseError)) #1 {main} thrown

and additionaly

Hi,
After making the edit from here:
https://github.com/horde/horde/commit/a77c83657a1398cbb7ed89408118460d8499ecd4
i was able to see the real error, which is this:
ParseError: syntax error, unexpected 'new' (T_NEW) in /usr/share/php/Services/Weather.php:167
I found a temporary fix here:
https://bugs.launchpad.net/ubuntu/+source/php-horde/+bug/1588787
which is purging php-services-weather and php-horde-service-weather
