Updating Packages behind prxy server in UBUNTU 11.10

Problem :  apt-get , Update Manager not able to download packages behind college/comapny proxy server.

Note : Sometimes there may be connection failure because of busy servers. So Please be patient during new Ubuntu release

Solution :
 
1) Open the Terminal and type the following command
     sudo gedit /etc/apt/apt.conf.d/02proxy

Note : 01proxy file is not present earlier.

2) Type the following line(in red) in the file:
     Acquire::http::Proxy “http://yourusername:yourpassword@yourproxy:yourport″;
    
Acquire::http::Proxy "http://foss:3189";
   


3) Save the file and your problem is solved.

  2. I almost gave up on having a working ubuntu behind proxy. Man, ubuntu is becomin like windows, with every new version more and more things work worse or don't work at all, but oh, it looks so much nicer x(.

    Anyway, tanks a lot

  5. Just a correction, In the example add semicolon at end of the line.

    Acquire::http::Proxy “http://yourusername:yourpassword@yourproxy:yourport″;

    **It worked fine**
    Thanks :)

  8. Didn't work, when running apt I get an error message referring to the 02proxy file created by following this guide which says "junk at end of file"

    This is a syntax problem. Please Check that all the symbols are correctly placed.

    1. you can put '\' in front of special characters. DO NOT USE QUOTES.

      Ex:
      Acquire::http::Proxy "http://yourusername:yourpassword@yourproxy:yourport″;

      Acquire::http::Proxy "http://yourusername:pass\@word@yourproxy:yourport″;

      This should work. Try and tell me whether this thing works or not.

  16. You should be able to quote a backslash with another backslash:

    SILLYDOMAIN\\user:p\@ssword@1.1.1.1:8080

    1. Do you have gedit installed in your system?

      You can follow these steps
      1. Go to /etc/apt/apt.conf.d/ folder.
      2. Create a file with name as 02proxy
      3. Enter the line given below by replacing your proxy settings.

      Acquire::http::Proxy “http://yourusername:yourpassword@yourproxy:yourport″;

      4. Save and exit
      5. END

  23. Hello I'm using Ubuntu server 12.04 behind a proxy, I was having trouble to do updates and that didn't work.
    However, I commented out that definition in file etc/apt/apt.conf (# Acquire::http::Proxy "http://yourproxy:yourport″;) and strangely that solved the issue.
    Now works fine. Go figure!

  24. Hello !

    I've had the same problem. My ubuntu box is behind a proxy and needs a user and password. Seems to work, if I use in System Settings -> Network -> Proxy
    the following for HTTP, HTTPS, FTP and Socks Host :

    proxy_username:proxy_password@proxy_ip

    instead of

    proxy_ip

    only.

    Example :

    bob:TopSecret@192.168.33.2

    bob = Proxy username
    TopSecret = Proxy Password of bob
    192.168.33.2 = Proxy IP

    and wohooo it worked

    Thanks man
