I was trying to apply "sudo apt-get update" command. However when I run the command, I get output like this;
berke@berke-ABRA-A5-V15-8:~$ sudo apt-get update

After this step I also tried to change the server as "Main Server". Yet, that didn't solve the time out error. What is the solution for this time out error in Ubuntu 20.04 Focal Fossa?
