My school network is behind a proxy server in which from campus, if I want to update my system through apt, I need to use authentication. For this I have created the file /etc/apt/apt.conf which contains the proxy authentication information as follows:
Acquire::http::proxy "http://username:password@server:port/";
Acquire::https::proxy "http://username:password@server:port/";
Acquire::ftp::proxy "http://username:password@server:port/";
Also, my password contains the special character $ which I have replaced with %24 from online recommendations. After running the command sudo apt-get update I am still getting the error:
407 Proxy Authentication Required
But I know my credentials are correct as I am able to login for normal browsing in Chrome/Firefox. Any ideas or suggestions on solving this problem?
/etc/apt/apt.conf? Is it the text from your question, or some specific server and port? – Pilot6 Aug 28 '17 at 11:50
