This question already has an answer here:
I was notified with a bunch of updates just half an hour ago, mostly security updates in nature. Without thinking much I authenticated the installation. It required me to reboot to apply the changes. After reboot I noticed that the network was not working. Please check the image below.
Also on restarting again I got a error message that Ubuntu has faced an internal error. Since my network is not working I couldn't send the crash report to Ubuntu. Please check the screenshot below.
I'm new to Ubuntu. Just a 1 week old user. I think if I can somehow revert back the Wi-Fi update, i.e., backport it may help to solve the situation. But I don't know how to or if that's the only solution. Please help me out.
