AH00072

Problem:
Previously working, but now
Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:443

Probable Cause:
Any two or more .conf files have Listen 443 or <VirtualHost _default_:443> in them.

Tentative Solution:
Edit your /etc/httpd/httpd.conf or other /etc/httpd/conf.d/*.conf files making sure you don’t have two files requesting port 443. It seems recent Apache versions are more strict and will fail to run, whereas older versions did not complain. Technically, I just the renamed /etc/httpd/conf.d/ssl.conf to /etc/httpd/conf.d/ssl.conf.OFF so that my actual /etc/httpd/conf.d/live_ssl.conf file was used.
  

a stop job is running for ifup | NetworkManager

Problem:
a stop job is running for ifup
a stop job is running for NetworkManager

Why:
Debian Jessie and jessie-backports systemd versions 2.15 and 2.30 respectively have a small bug that stalls shutdown.

Tentative Solution: (i.e. unofficial; your mileage may vary)
edit /etc/systemd/system/network-online.target.wants/networking.service, replacing

ExecStop=/sbin/ifdown -a --read-environment

with

ExecStop=/sbin/ifdown -a --read-environment --force --ignore-errors

and also

TimeoutStopSec=5min

with

TimeoutStopSec=5s
