I am currently struggling to try to run the command "sudo apt update" or "sudo apt-get update" I am assuming it might have something to do with the package repositories.

When I run the command, I get the following result below. I appreciate any sort of help you can provide. Thank you in advance.

E: Failed to fetch http://c.archive.ubuntu.com/ubuntu/dists/oracular/main/binary-arm64/Packages  404  Not Found [IP: 185.125.190.83 80]

I ended up changing settings in the "Software & Updates" application. In the "Other Software" tab, there was only two listed and selected. It had something to do with AMD architecture. I removed those, and I was able to run the command with no issues.
