During installation of Debian I was asked for a Standard Proxy String in the form of http://user:password@host:port/, which I entered. apt-get ran and retrieved files during update, and now Debian is installed. However, when I tried running sudo apt-get install ..., I get an error message containing the message Could not resolve proxy_host where proxy_host is the host I entered during installation.

Are there other places where I have to set up the proxy information?

  • 'Could not resolve' sounds more like a DNS or general networking problem. Can you resolve (and access, ping) the proxy host?

  • How do I test that? Everything worked fine during installation. -- Just read the ping part...

  • @sr_ I'm not able to ping the proxy host.

  • Your network settings might be incorrect, then. Have a look at the Debian Handbook's section on network configuration. (You could also be missing some firmware for your NIC.)

    How does your machine get internet access? Post the output of ifconfig and cat /etc/network/interfaces. Replace private information by placeholders if you like, but consistently (always the same placeholder for the same piece of information). Jul 9 '12 at 21:48

The following is for general proxy, apt and wget and you can remove the user:password@ for a proxy that doesn't require it:

For General proxy:

touch /etc/profile.d/proxy.sh

add the following:

export ftp_proxy=ftp://user:password@host:port
export http_proxy=http://user:password@host:port
export https_proxy=https://user:password@host:port
export socks_proxy=https://user:password@host:port

For APT proxy:

touch /etc/apt/apt.conf.d/99HttpProxy

add the following:

Acquire::http::Proxy "http://user:password@host:port";

For wget:

nano /etc/wgetrc 

find and uncomment proxy lines or add them if not present

http_proxy = http://user:password@host:port
https_proxy = ...
...

The http proxy information, entered during the set up, should (normally) end up in the file /etc/apt/apt.conf

Acquire::http::Proxy "http://user:password@host:port/";

  • It should be two colons :: between http and Proxy

Edit the bash.bashrc file and add the following lines to the bottom of the file:

export ftp_proxy="ftp://user:password@proxyIP:port"
export http_proxy="http://user:password@proxyIP:port"
export https_proxy="https://user:password@proxyIP:port"
export socks_proxy="https://user:password@proxyIP:port"
