I am using Ubuntu 18.04 desktop. I wanted to use Python 3.7 so I installed it and uninstalled Python 3.6, but it was a big mistake because now all my programs are acting weirdly.
I restarted my PC now I only running with the terminal. I tried sudo apt-get update but it fails to reach the Ubuntu server.
I tried with ping to 8.8.8.8 and it says Connection: Network is unreachable.
I search around on this forum, but there seems to be no answer for me until now. Here is the error screen.
What I have tried:
ifconfig => That command is not supported. Follow the answer here
sudo dpkg-reconfigure firmware-linux-free => firmware-linux-free not installed. Follow the answer here
I tried to clean the NetworkConfig as the answer is here
I reached to this answer however, I don't find any repo in the list so I don't comment anything.
Do you have any idea how to get the network back? After that, I will try to reinstall other software.
