NOTE: This error only occurs when I am connected to my home wifi. When using another wifi it seems to work just fine (no errors at all).

What could be causing this? And are there any fixes?

Thanks.

Can you remove some of the repositories as they have been deprecated? Re run updates – Akshat Zala Jun 17 '20 at 06:39
@AkshatZala how do I know which repository is deprecated? – Vasu Gupta Jun 17 '20 at 06:43
@AkshatZala Alright I removed a bunch of repositories, and I am no longer getting the errors. Thanks! – Vasu Gupta Jun 17 '20 at 06:50
