I usually connect to the internet via USB on my laptop running Ubuntu 18.04. Before the login screen, I can see I have access to the internet. If I press CTRL+ALT+F2 and go to the tty2 screen, I can manually log in and access the internet (for instance, I can run
sudo apt-get update without problem).
However, recently I have noticed that once I log in, the connection drops and network-manager is never able to connect again. It endlessly crashes at the
Network activation part.
What is wrong with it?
