[SOLVED]Error poking ModemManager: GDBus.Error:org.freedesktop.systemd

every 2 mins I get this message in the /var/log/user.log file

May 13 15:07:47 localhost NetworkManager[235]: <warn> error poking ModemManager: GDBus.Error:org.freedesktop.systemd1.LoadFailed: Unit dbus-org.freedesktop.ModemManager1.service failed to load: No such file or directory. See system logs and 'systemctl status dbus-org.freedesktop.ModemManager1.service'  for details.

I do not have any modem, so I'm not sure if this ModemManager should be on or not. how can I disable this message?

Did you perform the diagnostics recommended in the warning message you posted?  Will you please post the outputs of those commands?

Re: [SOLVED]Error poking ModemManager: GDBus.Error:org.freedesktop.systemd

here is the result of the command

[root@artemide ~]# systemctl status dbus-org.freedesktop.ModemManager1.service
dbus-org.freedesktop.ModemManager1.service
   Loaded: error (Reason: No such file or directory)
   Active: inactive (dead)

but I think normal that it's inactive, because I do not have any modem that have to be managed...
I think that this is a false message, and I do not have to activate anything more than I already have. but it is annoyng to see in the error log this error message every 2 mins.

do you agree?

I agree, but...   Do you have the ModemManger1.service enabled?  If so, disabling it might fix your problem.

Failed to issue method call: No such file or directory

[root@artemide ~]# systemctl stop dbus-org.freedesktop.ModemManager1.service

Re: [SOLVED]Error poking ModemManager: GDBus.Error:org.freedesktop.systemd

Hi adee,
i take it as a workaround, as the fix say

"do systemctl start ModemManager.service and systemctl enable ModemManager.service"

and I actually do not like to activate a modem manager, if I do not have any modem that have to be manage, but just for stop tu full the logs

do you know when this will be fixed?

Re: [SOLVED]Error poking ModemManager: GDBus.Error:org.freedesktop.systemd

I have this issue too and solved moving the /usr/share/dbus-1/system-services/org.freedesktop.ModemManager1.service to my backup folder...

/usr/share/dbus-1/system-services/org.freedesktop.ModemManager1.service

I too got rid of that problem after removing that file. That file doesn't seem to be very useful, and it fills up the log (I don't have a modem).

# This D-Bus service activation file is only for systemd support since
# an auto-activated ModemManager would be quite surprising for those people
# who have MM installed but turned off.  Thus the Exec path available to
# D-Bus is /bin/false, but systemd knows the real Exec path due to the MM
# systemd .service file.

[D-BUS Service]
Name=org.freedesktop.ModemManager1
Exec=/bin/false
User=root
SystemdService=dbus-org.freedesktop.ModemManager1.service

It seems this problem is only affecting Arch Linux, because googling the error message shows only Arch or Arch-based distributions results.
Maybe https://bugs.archlinux.org/task/34971 is a real bug. But, whose fault is that?

Re: [SOLVED]Error poking ModemManager: GDBus.Error:org.freedesktop.systemd

I think removing the file in /usr/share/dbus-1/system-services will certainly do the trick.  But I went ahead and used ABS to build networkmanager w/o the "--with-modemmanager" in the ./configure section.  I also took modemmanager out of the depends array.  Then I put in a group array into the PKGBUILD, in which I added it to a group called "modified" so that I can ignore this group in pacman.conf.  In this way I don't automatically pull in new versions of networkmanager that will also pull in modemmanager, but I still get notified by pacman that it is skipping this update because it is in the IgnoreGroup section.  (Thanks for this idea jasonwryan).

Whoa! I commend the fact that you actually came back here to report the success, even if it has been several months.  Good work milky76!

Then I put in a group array into the PKGBUILD, in which I added it to a group called "modified" so that I can ignore this group in pacman.conf.  In this way I don't automatically pull in new versions of networkmanager that will also pull in modemmanager, but I still get notified by pacman that it is skipping this update because it is in the IgnoreGroup section.  (Thanks for this idea jasonwryan).

Thanks, This trick is great,
