I tried letting ubuntu troubleshoot it
sudo mv /etc/apt/sources.list ~/
sudo touch /etc/apt/sources.list
software-properties-gtk
but after tring to cofigure the "ubuntu software" window by checking "Community- maintained and open source software" and changing the download server to "server for united states" and "updates" window by subscribing to all updates but i got the following error:

I proceeded anyway and updated the "/etc/apt/sources.list" file and then i tried to update again with "sudo apt update" but got:

I also tried to install y-ppa-manager but i got the same errors and couldn't finish the installation.
I am new to linux and can't find the solution to this problem.

sudo apt-get update
