I got the same problem, apache2 doesn't start after the update to 2.4.18-2ubuntu3.18. I got the same output as in Comment 25. I noticed the problem in the browser when I couldn't get to my locally served web pages.
$ uname -m x86_64 $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.7 LTS Release: 16.04 Codename: xenial I also had to downgrade to get apache2 running again, using: aptitude install apache2-bin=2.4.18-2ubuntu3.17 apache2-data=2.4.18-2ubuntu3.17 apache2=2.4.18-2ubuntu3.17 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832182 Title: systemd unable to detect running apache if invoked via "apache2ctl graceful" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1832182/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
