W: Failed to fetch 404 Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

I want to make sure I pass the sanity tests before upgrading.

Ignore this.

ignore it? but my whnix hasnt updated in weeks because of this.

Because wheezy based Whonix is deprecated. You don’t need that repo.
Just follow the instructions on Release Upgrade - Whonix.

Good day,

furthermore, may I add that simply typing “sudo apt-get update” doesn’t necessarily update anything on your system. Updates only get downloaded and applied when also using “sudo apt-get upgrade” (or dist-upgrade depending on the situation). That’s one of these things, which are different, depending on the system (and mainly the package manager). On Fedora, for example, typing “sudo yum update” does both fetch the lists and update everything at once. On Debian-based systems like Whonix or Ubuntu, both can be done at once by typing: “sudo apt-get update && dist-upgrade”.

Have a nice day,
