Network Manager fails to restart due to timeout exceeded

sx flag

My ubuntu 18.04 LTS was working fine. Next thing, wifi symbol disappears and it says "NetworkManager needs to be running" in settings.

So I used restart command (sudo /etc/init.d/network-manager restart) and output is:

Restart cmd output pic

Then I used the below commands :

systemctl status NetworkManager.service

and

journalctl -xe

Here are the outputs for the respective commands.

Systemctl status output pic

Journalctl output pic

Please let me know what more commands I can run and see.

Sorry for the formatting and images, I'm using phone as I'm unable to access wifi on my laptop.

P.S Restarting didn't work.

Welcome to AskUbuntu, next time you can copy and paste the text output, instead of taking photo of the display.

I don't have internet on laptop, hence using my phone. Sorry.

It's okay. I understand that you can't do it for now. By the way, I probably found the answer. https://askubuntu.com/questions/882806/ethernet-device-not-managed

you can restore the wifi icon by typing nm-applet, then

sudo systemctl stop network-manager
sudo systemctl start network-manager

nm-applet says `NetworkManager is not running` and running systemctl start network-manager gives same error as my restart screenshot above.

First try to simply start that

sudo systemctl start NetworkManager.service

if it doesn't check the configuration files.

/etc/NetworkManager/NetworkManager.conf


Some people mentioned, unmanaged devices caused failure. Ethernet device not managed

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
