I've got a fresh Ubuntu 17.04 server, I've configured networking and can resolve all addresses as I'd expect, however when I run sudo apt update I get to ~19% at which point I get a load of messages indicating failures, such as...
err http://security.ubuntu.com/ubuntu zesty-security release 404 not found [91.189.88.162 80]
and then
Repository http://security.ubuntu.com/ubuntu zesty-security does not have a release file
this is repeated several times.
All the listed URIs are reachable/resolve from terminal.
sudo apt-get upgrade

The problem is that without updates I can't get any other packages to install and I'm not familiar enough with linux to deal with it. Anyone got any thoughts on why updates aren't taking?
I know I'm supposed to be on 17.10 by now but I was hoping that'd be able to be sorted with an upgrade!
