Network Manager fails to restart due to timeout exceeded

Question

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:

Then I used the below commands :

systemctl status NetworkManager.service

and

journalctl -xe

Here are the outputs for the respective commands.

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. — Sadaharu Wakisaka, Jan 22 '22 at 02:21
I don't have internet on laptop, hence using my phone. Sorry. — PolPaul, Jan 23 '22 at 04:16
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 — Sadaharu Wakisaka, Jan 24 '22 at 00:07

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. – PolPaul Jan 22 '22 at 07:51

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
