[Solved]Stopping dhcpcd and starting Network Manager fails

cdrjameson · 2014-04-09 09:43:07

Stock Arch with cinnamon desktop. I normally use dhcpcd to connect to a wired connection. I am trying to use the nm-applet to manage connections.

I have followed the wiki and plethora of forum posts and external blogs on this issue, but nothing is working for me.

I have installed network-manager-applet and networkmanager. The only network service I have running is the dhcpcd service:

cdr ~ $ systemctl --type=service

To my knowledge there aren't any more network services running that could interfere with network manager. I stop and disable dhcpcd:

cdr ~ $ sudo systemctl stop dhcpcd
[sudo] password for cdr: 

cdr ~ $ sudo systemctl disable dhcpcd
rm '/etc/systemd/system/multi-user.target.wants/dhcpcd.service'

I am a member of the wheel group which according to the wiki(Network Manager) should give me the necessary permission to set up a session.

cdr ~ $ sudo systemctl enable NetworkManager
ln -s '/usr/lib/systemd/system/NetworkManager.service' '/etc/systemd/system/dbus-org.freedesktop.NetworkManager.service'
ln -s '/usr/lib/systemd/system/NetworkManager.service' '/etc/systemd/system/multi-user.target.wants/NetworkManager.service'
ln -s '/usr/lib/systemd/system/NetworkManager-dispatcher.service' '/etc/systemd/system/dbus-org.freedesktop.nm-dispatcher.service'

cdr ~ $ sudo systemctl start NetworkManager

I have manually added the applet to the tray, (dont think I should need to do this but it wasn't showing up) and it recognises my interfaces. It still shows as disconnected, after I

cdr ~ $ sudo ip link set enp4s0 up

when I toggle the switch on the app to 'on' it automatically reverts to 'off' with a notification that connection failed.

If I use the launch nm-applet from a terminal I receive

** (nm-applet:1313): WARNING **: Could not initialize NMActiveConnection /org/freedesktop/NetworkManager/ActiveConnection/17: Method "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties" doesn't exist

** (nm-applet:1313): WARNING **: Could not create object for /org/freedesktop/NetworkManager/ActiveConnection/17: Method "GetAll" with signature "s" on interface "org.freedesktop.DBus.Properties" doesn't exist

My NetworkManager.conf:

[main]
plugins=keyfile
managed=true
dhcp=dhcpd
no-auto-default=BC:5F:F4:B9:EE:5A,

and the output from ip addr:

...
2: enp4s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether bc:5f:f4:b9:ee:5a brd ff:ff:ff:ff:ff:ff
    inet6 fe80::be5f:f4ff:feb9:ee5a/64 scope link 
       valid_lft forever preferred_lft forever
...

Really trying to not be a help vampire, but I do need help.

You have a typo in NetworkManager.conf. It should be "dhcp=dhcpcd". I'm not sure about the comma after the MAC address in it either.

It is the typo Strike0 has mentionned. 100% sure. And the comma too. You only need the comma, if you want to separate multiple MAC addresses with it.
