Description of problem:
Trying to start, stop, restart services with systemd fails and emits errors like:
Error getting authority: Error initializing authority: Error calling StartServiceByName for org.freedesktop.PolicyKit1: GDBus.Error:org.freedesktop.DBus.Error.TimedOut: Activation of org.freedesktop.PolicyKit1 timed out (g-dbus-error-quark, 20)

Based on the following logs it seems that the issue could be with systemd and not specific to polkit :
Jan 25 17:19:28 localhost systemd-logind: Failed to fully start up daemon: Connection timed out
Jan 25 17:19:28 localhost dbus[908]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out

The line "Jan 25 17:19:28 localhost dbus[908]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out" seems to be pointing to the issue.
On checking for issues reported for upstream, I could see systemd being responsible for the issue. Following are the upstream reported issues:
https://github.com/systemd/systemd/issues/2019https://bugs.freedesktop.org/show_bug.cgi?id=93066https://github.com/systemd/systemd/issues/2925
I don't think that logind would block systemctl start/....
This seems to be a bigger problem:
Jan 25 17:19:28 localhost dbus-daemon: dbus[908]: [system] Failed to activate service 'org.freedesktop.systemd1': timed out
I have the exact same problem with a server I just updated.
My version number are different (except for dbus is the same):
polkit-0.112-12.el7_3.x86_64
systemd-219-42.el7_4.4.x86_64
kernel-3.10.0-693.11.1.el7.x86_64
The problem seems to be polkit that can't start org.freedesktop.PolicyKit1
Here is a part of the start of polkit:
polkitd[139162]: Acquired the name org.freedesktop.PolicyKit1 on the system bus
systemd[1]: polkit.service start operation timed out. Terminating.
Failed to start Authorization Manager.
dbus and other services are not starting for this reason. I googled the problem and didn't see anything.
I am not using SELinux, so this is not the problem.
And I reinstall polkit just in case: yum reinstall polkit
And reinstall dbus too, just in case!
I checked that all the rules in /etc/polkit-1/ are exactly the same with exact same permission as 1 year ago. Done!
There is a bug in the way that polkit is started (is it in polkit? dbus? systemd?)
A strace of the start of polkit seems normal until at the end it loops on:
poll([{fd=5, events=POLLIN}, {fd=8, events=POLLIN}], 2, -1) = 1 ([{fd=5, revents=POLLIN}])
read(5, "\1\0\0\0\0\0\0\0", 16) = 8
with sometimes this line appears:
futex(0x560d2fca1d50, FUTEX_WAKE_PRIVATE, 1) = 1
So there is a real bug in the updates because it was working perfectly before the update.
Problem solved!
I don't know if your problem was the same, but mine was that setroubleshoot user was absent from the /etc/passwd
setroubleshoot-server was complaining it could not be updated because the setroubleshoot group was there but not the user. So I removed the group, reinstall setroubleshoot with an update. After I restart by hand (with systemctl) all other failed deamon beginning with polkit, and voila!
Hope this helps you find your problem.

Anyone else pulling their hair out with this issue - run a quick pwck and see if anything is amiss. Due to a fat-finger search and replace, I managed to remove the home directory field for systemd-network and polkitd, making both accounts invalid and systemd/polkitd very upset.
