Can't start NetworkManager

Postby MasterF » 13 Jul 2014 12:38

Hello,

I'm on SolydK and I've recently started having trouble with NetworkManager. It simply won't start.
The networking widget in the tray displays "NetworkManager not running". This started occuring after I've added a DSL connection through the GUI.

As you can see below, I've tried to manually start the service, but it's no use. I also don't get any error messages to investigate (or maybe I don't know where to look for them).

Code: Select all

masterf-pc ~ # whoami
root
masterf-pc ~ # service network-manager status
[FAIL] NetworkManager is not running ... failed!
masterf-pc ~ # service network-manager start
[ ok ] Starting network connection manager: NetworkManager.
masterf-pc ~ # service network-manager status
[FAIL] NetworkManager is not running ... failed!
masterf-pc ~ # NetworkManager 
masterf-pc ~ # echo $!

masterf-pc ~ # ps -ef | grep -i net
root        28     2  0 12:04 ?        00:00:00 [netns]
root     14744 14056  0 15:29 pts/1    00:00:00 grep --colour=auto -i net
I can get my Internet connection to work by manually doing "ifconfig eth1 up" and "dhclient eth1", but I would really want to get NetworkManager working again. I've also tried removing and reinstalling all it's packages (not Complete removal though).

Thanks in advance for any assistance.

Code: Select all

inxi -Fxz
dpkg -l |grep network
systemctl list-units |grep etwork
systemd-analyze critical-chain
in case if you're not using systemd yet you can skip the last two command and replace the command with "nm-applet".

Here's the output for the first two commands. I'm not running systemd.
I can't find any "nm-applet" command on my system.

you can install it by "sudo apt-get install network-manager-gnome".

I've tried the "sudo apt-get install network-manager-gnome", but it wants to pull in 111 packages (most of the Gnome desktop, I guess). Is it that important? I'd prefer not to install over 100 new packages I probably won't use.

Also, as far as I understand it's just another front-end that uses the NetworkManager daemon.

it's "just" the front-end of network-manager but it also "the only" stable frontend :3
there's only two network manager front-end in debian (this package and plasma-nm). you can use plasma-nm as an alternative but it's a new package and might not stable as gnome's nm-applet.

anyway, 100 dependencies is too much. something is fishy about your apt setting. please try to turn off recommended package setting. gnome's nm-applet indeed have lot's of dependencies but it's less than 30.

I tried it without the consider recommended packages as dependencies setting, but it was the same.

Anyway, I found a way to get it to work: I removed all the connections from /etc/NetworkManager/system-connections. After a restart, NetworkManager was working. It seems if I set a DSL connection it crashes when I try to connect. For now, I'm letting my router handle it and just using regular DHCP. It's not optimal since I have a 1 Gbps connection but the router can't handle that much.

I'll try setting up the DSL again next week.

I just installed the latest update pack and my DSL connection works now.
