proxy setting

[dannyhmui]

Dear friends, I just setup Debian 9 on my virtual machine and use NAT to share host IP, I can also assign an IP to this VM if I want to. now, I can access internet, but I am not able to install any application because missing a lot dependencies.
for my other windows VM, I need to set proxy.xxxx.local 8080 in internet connection tab, then add proxy.xxxxx.site then input logon name and pass for credential to get online. I am wondering how to do this in my debian?

when I try to do sudo apt-get update, I got:

Code: Select all

E: Failed to fetch http://ftp.au.debian.org/debian/dists/stretch/main/i18n/Translation-en  Could not resolve 'auth.xxxxxxx.local'
