This issue has come up for me in FC25 after I disabled NetworkManager.service to use the plain network service.
NetworkManager.service had to be disabled because of an issue I was having with V6/Sendmail/NetworkManager reported in a separate bug (1409596).
+++ This bug was initially created as a clone of Bug #1141961 +++
Description of problem:
When NetworkManager and NetworkManager-wait-online are disabled (using the
plain network service instead), missing dependencies on
NetworkManager-wait-online are reported during boot.
Version-Release number of selected component (if applicable):
How reproducible: Always
Steps to Reproduce:
1. Disable NetworkManager and NetworkManager-wait-online with systemctl.
2. Configure the network service.
The following error is logged:
# grep -B1 DEPEND /var/log/boot.log
[ INFO ] Network Manager is not active.
[DEPEND] Dependency failed for Network Manager Wait Online.
Since NetworkManager is disabled, there should be no related error messages during boot.
Closely related to
NetworkManager-wait-online reports dependency errors
when using network.service
which was closed for Fedora 19 because the warnings magically disappeared.
However, the bug is still present in Fedora 20.
Quite likely, the culprit is the NetworkManager-provided symlink
In fact, removing this symlink eliminates the
"Dependency failed for Network Manager Wait Online."
Note that network.service Wants network-online.target, which is ordered After NetworkManager-wait-online.service (OK). However, there should NOT be a
network-online.target Wants ---> NetworkManager-wait-online.service (1)
dependency, because NetworkManager-wait-online.service cannot be started given that we've disabled NetworkManager.
Also related is
NetworkManager-wait-online.service should pull in network-online.target
C1 (2013-08-28) confirms that a
NetworkManager-wait-online.service Wants ---> network-online.target (2)
relation -- the reverse of the above relation (1) -- should actually be present and soon be in Fedora 20.
However, that is not yet the case:
# systemctl show -p "Wants" NetworkManager-wait-online.service
which is confirmed by the .service file:
# cat NetworkManager-wait-online.service
Description=Network Manager Wait Online
Wants=network.target # ==> Should be: Wants=network-online.target
ExecStart=/usr/bin/nm-online -s -q --timeout=30
Is the fix for NetworkManager-wait-online.service perhaps stuck somewhere upstream?

There was a discussion about NetworkManager-wait-online.service in bug 1076053. Unfortunately, it was not finished and decided whether the unit is right at that time. So lets ask systemd guys once more how the unit should look like.

I don't think that there is a clean solution. I would suggest to leave things as is in released fedoras. And that drop the symlink and set WantedByt to network-online target, maybe also have the Also to this unitfile in NetworkManager service.

This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 20 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
I am gonna close this. There is not enough fresh information attached to this bug.
The cloned bug 1141961 is very old. Very likely that issue there is already fixed and whatever you see, has a different cause. Even if the underlying cause happens to be the same as bug 1141961, it would require a fresh analysis (including debug data) -- because apparently the provided information is not yet enough to solve it.
This could however be the same issue as bug 1455704. In that case, it's due to NetworkManager.rpm always installing /usr/lib/systemd/system/network-online.target.wants/NetworkManager-wait-online.service.
The workaround could be to delete that file (which you could do to test the issue, it isn't a real solution because package-update would restore the file).
Alternatively do `systemctl mask NetworkManager-wait-online.service`.
