Disabled all 3rd party sources in your repositories first.
sorry.I am a noob .can you please guide me
I can see from the output that the errors are related to 3rd party sources you have added to ZorinOS. Go to software center and click the burger menu. Pick repositories. Here you can add/edit/remove sources that software center/Zorin OS are using. You can try remove the offending sources.
