"Unknown error" while signing in to Apple App Store

I was unable to log in to the Apple App Store while trying to update Xcode on my MBP.

Here's an Apple discussion thread regarding possible solutions.

What ended up working was signing out, clicking "Store -> Create New Account", accepting the Terms and Conditions, then canceling out of new account creation and signing in again.

While deleting the network interface plist, cookies, etc. was educational, it didn't work.

Accepting T&C while not creating a new account so I could use my old one... "It just works"?

This helped me, there was an account already signed into the App Store when I tried to sign in with my account. Instead of it saying "you have to log out first" or something, it just prompted me to log in and then gave me the Unknown Error. So this is a variation on what the OP describes.
