Hello, a few days ago php-fpm from packages.sury.org repository started to require systemd. Our Debian 9 was installed without systemd and it was impossible to upgrade to latest version of PHP. Solution is quite simple and it is described here: https://github.com/oerdnj/deb.sury.org/issues/1347 In short it is necessary to disable install recommends and than install systemd. It works fine. But after that ISPConfig detect systemd and try to restart services using systemd which fails: Code: DEBUG - Apache status is: running DEBUG - Calling function 'restartHttpd' from module 'web_module'. DEBUG - Restarting httpd: systemctl restart apache2.service DEBUG - Apache restart return value is: 1 DEBUG - Apache online status after restart is: running WARNING - Apache did not restart after the configuration change for website domain.tld. Reverting the configuration. Saved non-working config as /etc/apache2/sites-available/domain.tld.vhost.err WARNING - Reason for Apache restart failure: Failed to get D-Bus connection: Unknown error -1 DEBUG - Calling function 'restartHttpd' from module 'web_module'. DEBUG - Restarting httpd: systemctl restart apache2.service When I comment out systemd section of _getinitcommand function in /usr/local/ispconfig/server/lib/classes/system.inc.php it works without error message. I know that systemd is preferred init now, but maybe there could be more precise way to find out which init is used. It is discussed here for example: https://unix.stackexchange.com/ques...ystem-uses-sysv-upstart-or-systemd-initsystem
