I'm trying to upgrade a 16.04 system. When I do:
sudo apt-get upgrade
I get:
Err:1 http://us.archive.ubuntu.com/ubuntu xenial-updates/main amd64 libc6-dbg amd64 2.23-0ubuntu9 404 Not Found [IP: 91.189.91.23 80]
and many more like it.
I did sudo apt-get update
, but got similar messages:
E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/xenial/main/binary-arm64/Packages 404 Not Found [IP: 91.189.91.23 80]
Output of --print-architecture:
amd64
Output of --print-foreign-architectures:

arm64
I'm pretty new to Ubuntu.
