I made the mistake of upgrading to Ubuntu Xenial and somehow the software for Koha no longer are available from a web browser. I have concluded that the problem seems to be in the Apache2 application. I am receiving the following error messages: ● apache2.service - LSB: Apache2 web server Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled) Drop-In: /lib/systemd/system/apache2.service.d └─apache2-systemd.conf Active: failed (Result: exit-code) since Tue 2017-05-16 14:46:56 PDT; 17min ago Docs: man:systemd-sysv-generator(8) May 16 14:46:56 ubuntu apache2[19130]: * The apache2 configtest failed.

My system is down until this is resolved or I reinstall trusty and rebuild my library. Any help would be greatly appreciated. I hope I am the only one to have run into this problem, but I think not.
