Need assistance in resolving above issue

1. This is a user issue, not a Kali issue. Fix your DNS/internet.
2. Stop using root.

I tried to execute using the command through sudo, but still getting the same error and below is the resolv.conf details.

┌──(pe㉿)-[~]
└─$ sudo apt-get update

nameserver 8.8.8.8

Again, this has to do with you and your networking. Try:

• ping 8.8.8.8
• ping google.com
• nslookup google.com

If the latter 2 commands fail, the issue is in your DNS. This is not a Kali issue but a user issue.

Thank you for your interest in Kali but this is not a bug report. It looks like that you need help and guidance to perform some task.
