    But when the proxy requires an authentication like “domain\user”?
    This is my problem, and the terminal dosn’t pass the authentication:
    http://domain\user:pass@proxy:8080/ (configured “OK” in firefox)

    Setting up apt-get to use a http-proxy

    These are three methods of using apt-get with a http-proxy.

    Temporary proxy session

    This is a temporary method that you can manually use each time you want to use apt-get through a http-proxy. This method is useful if you only want to temporarily use a http-proxy.

    Enter this line in the terminal prior to using apt-get (substitute your details for yourproxyaddress and proxyport).

    export http_proxy=http://yourproxyaddress:proxyport

    APT configuration file method

    This method uses the apt.conf file which is found in your /etc/apt/ directory. This method is useful if you only want apt-get (and not other applications) to use a http-proxy permanently.

    IconsPage/info.png On some installations there will be no apt-conf file set up. This procedure will either edit an existing apt-conf file or create a new apt-conf file.

    gksudo gedit /etc/apt/apt.conf

    Add this line to your /etc/apt/apt.conf file (substitute your details for yourproxyaddress and proxyport).

    Acquire::http::Proxy “http://yourproxyaddress:proxyport”;

    Save the apt.conf file.

    BASH rc method

    This method adds a two lines to your .bashrc file in your $HOME directory. This method is useful if you would like apt-get and other applications for instance wget, to use a http-proxy.

    gedit ~/.bashrc

    Add these lines to the bottom of your ~/.bashrc file (substitute your details for yourproxyaddress and proxyport)

    export http_proxy

    Save the file. Close your terminal window and then open another terminal window or source the ~/.bashrc file:

    source ~/.bashrc

    Test your proxy with sudo apt-get update and whatever networking tool you desire. You can use firestarter or conky to see active connections.

    If you make a mistake and go back to edit the file again, you can close the terminal and reopen it or you can source ~/.bashrc as shown above.

    source ~/.bashrc

    How to login a proxy user

    If you need to login to the Proxy server this can be achieved in most cases by using the following layout in specifying the proxy address in http-proxy. (substitute your details for username, password, yourproxyaddress and proxyport)

    Building dependency tree
    Reading state information… Done
    Package graphviz is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    E: Package ‘graphviz’ has no installation candidate

    I have made a video for Setting Simple and Authenticated Proxy Settings in Ubuntu 12.04/12.10/13.04/13.10/14.04/14.10 and above 100% Working.

  11. Ironyman says:

    These instructions will configure FIREFOX/mozilla to use the proxy server. The instructions here DO NOT configure Ubuntu to use your proxyserver. In other words, everything that does not use Firefox will be unaffected.

  12. Peter says:

    Ludicrous. great that you have ALL the ways of setting the proxy, but why is the first one “System—>Preferences—>Network Proxy” not the only one needed.

    why do you then need to go on and set all the others. The O/S is broken if you got to set it in more than one place, Before you rant, Firefox should default to “system settings” and the package manager is PART of the system.

    absolutely bizarre.

    FWIW you left out what file is updated when you use “System—>Preferences—>Network Proxy”

  13. I made a tool to simplify the entire task. You can download it from himanshushekharb16/ProxyMan ( << this link
    Also, you can have a look at the code if you are more interested to know the backend functioning.
    Download the zip file,extract them, go to the location of extracted files in terminal and following commands would help you:
    bash : *to set and unset proxy.*
    bash : *to check your current proxy settings.*
