I have tried looking up every possible Ubuntu update problem forum, however I cannot seem to find anything that works. I cannot seem to figure out how to fix the issue where it keeps saying the packages or files with Zesty are unable to be found. Below I have copied the code I get when I type in sudo apt-get update.

End of life for 17.04 was January 13, 2018. The repositories have been moved to a different location and must be accessed differently.

You should upgrade to 17.10 or install a long term support version like 16.04. Then you can continue with whatever you were trying to do.
