You need to completely remove apt.kubernetes.io repository from your system. See #3485 for more details.

I am unable to figure out from where apt.kubernetes.io is being picked up. Please help me with it

You still have apt.kubernetes.io and/or packages.cloud.google.com/apt kubernetes-xenial enabled on your system. It might not be necessary in /etc/apt/sources.list.d/kubernetes.list, it might be in some other location. We can't help you much there, but I recommend inspecting what repositories you have enabled in /etc/apt/sources.list and /etc/apt/sources.list.d
