[Chris Martin]

running apt-get update: [ discussed in question #223040 ]

i have tried/etc/apt/apt.conf.d/80proxies with contents:

  Acquire::http::proxy "http://ipv6onlydqdn:port/";

and when this didnt work tried:

  Acquire::http::proxy "http://[ipv6address]:port/";

both times i see the following messages:

How to configure http proxy with IPv6 address in apt.conf.

Is following syntax correct?

Acquire::http::proxy "http://[2008::103]:80/";
Acquire::https::proxy "https://[2008::103]:80/";
