Systemd units failed to start

From time to time I'll get a message (or messages) to the effect that a particular unit failed to start. Most of the time this is the result of some preordained Ubuntu configuration being out of sync. This gist will contain a running list of those as they come up.

To see a list of failed units:

$ sudo systemctl list-units --state=failed

Here's the list of failed units on my latest (2019/04/04) update and reboot:

NetworkManager-wait-online.service The server is question is not using NetworkManager, but instead ifupdown and the networking service. Set this unit to disabled.

isc-dhcp-server6.service Not doing ipv6 networking on the local network, so disabled this unit.

cgmanager.service Per this post on the lxc issues list, cgmanager is not needed if you're running systemd. This unit now disabled.
