As @Aravisian asked me to do I switched to main server in Repositories from Ubuntu and Zorin are really slow - #10 by Aravisian I switched to main server and got this error message
It was too big to fit in my screen and I saw no scroll bars. I successfully switched to main server. Then can I ignore this error message. Also I got this after I did the switching part, the one where you get the message that soome things are outdated or something like that. I don't remember correctly.
