You configured apt to use a proxy running on your own computer (localhost, port 
8080). Probably you're not running a proxy.
You should delete the proxy.conf to allow apt to connect directly.

The proxy should be a http(s) proxy, not a DNS server.

Just delete the proxy.conf, unless you really need a proxy to make the 
connection, and if so, you should first configure the proxy (apache, nginx, 
whatever).
