Comment 6 for bug 2025978

Here's the settings I used. This works with the current edge version of the charm:

apt-ftp-proxy model http://10.76.244.153:8080/
apt-http-proxy model http://10.76.244.153:8080/
apt-https-proxy model http://10.76.244.153:8080/
apt-mirror default ""
apt-no-proxy default ""
ftp-proxy default ""
http-proxy default ""
https-proxy default ""
no-proxy default 127.0.0.1,localhost,::1
juju-ftp-proxy model http://10.76.244.153:8080/
juju-http-proxy model http://10.76.244.153:8080/
juju-https-proxy model http://10.76.244.153:8080/
juju-no-proxy default 127.0.0.1,localhost,::1

This is using both the apt-*-proxy settings and the juju-*-proxy settings and works fine for me. Please confirm (as I asked previously) that the apt-*-proxy settings are set, because these are used for add-apt-repository and other apt-related networking.
