[Solved] Job for NetworkManager.service failed because the control process exited with error code.

[WaltzNightray]

Hello guys,

Having some issues with Network-Manager which is not starting, although I strangely do still have networking.

Here is the result for trying to start it

Code: Select all

sudo systemctl start NetworkManager
Job for NetworkManager.service failed because the control process exited with error code.
See "systemctl status NetworkManager.service" and "journalctl -xeu NetworkManager.service" for details.

And here is the result of journalctl

Code: Select all

journalctl -xeu NetworkManager.service

All I get is that this job is failing to start or finish, but not sure on what is it.

Any ideas on how to solve it is greatly appreciated.

Hello,

Maybe the suggested command:

Code: Select all

systemctl status NetworkManager.service

could give you more clues.

Not so much to work with, at least at first glance

Hello,
You can try:

Code: Select all

script NetworkManager.log
sudo /usr/sbin/NetworkManager --no-daemon --log-level=DEBUG
sudo journalctl -b --no-pager -u NetworkManager.service
exit

The logs should be in the file named NetworkManager.log

Aki,

Thanks for your help! I found out that there was configuration file for my VPN in the /conf.d folder being loaded together with the NetworkManager config. Not sure how this messed up the service, but removing that file from there solved the issue and NetworkManager service is fine now.

My VPN is not connecting anymore, but I can use it in another computer, so it's kinda fine now...

Thank you very much, this may be considered as resolved for now.
