Configure apt-get to work behind a proxy in Ubuntu 10.04 Lucid Lynx

Written by Mel Kham on April 24, 2010. Posted in Linux tutorials

How to apply apt-get update or install in Ubuntu 10.04 Lucid Lynx ? I was behind a proxy server and after installing Ubuntu 10.04 Lucid lynx i coulden`t update or install anything using the apt-get command. After searching i found that The apt package has been changed, now there is no more apt.conf on /etc/apt directory.

What i did to resolve this issue is the follow :

Open terminal and the file /etc/bash.bashrsc

sudo gedit /etc/bash.bashrc

and add at the bottom of the file these 2 lines :

#proxy 
export http_proxy=http://user:password@host:port/
export ftp_proxy=http://user:pass@host:port/

Now save and exit

Now you will be able to update, upgrade or install packages in Ubuntu 10.04 Lucid Lynx

this is the way it worked for me:

add to /etc/apt/apt.conf (create new if not existing)

Acquire::http::Proxy “http://proxy.example.com:8080/”;
udippel

The idea is okay, but on any ‘strict’ authentication (NT instead of LM), this method “http://user:pass…” will not work.

This did not work for me. Nor did creating an apt.conf file.

Any help?

  Alas, the *nix got kind of stuck at the basic NTLM out of the box. It is high time in the area of Microsoft Forefront and other, ‘advanced’ filters, that *buntu gets a default authentication mechanism for NTLMv2 and sorts.
  [/Rant]
  
  What helped here, was a longer, two-pronged trip:
  1. cntlm for authentication (it is in the repository)
  2. using aptitude, since apt-get is also very basic, and limited to more or less direct Internet connections.
  Like:
  sudo aptitude -o Acquire::http::Proxy=http://127.0.0.1:3128 update|safe-upgrade
  Eventually, you need extra options, like
  -o Acquire::http::No-Cache=True -o Acquire::BrokenProxy=True
  
  But first, make sure that you have a properly working cntlm!

    Thnxx dude uddpl i was eager to get it working since 4 dayzz it worked finally "sudo aptitude -o Acquire::http::Proxy=http://127.0.0.1:3128 update|safe-upgrade"
    
    :evil:
    
    i m amazed y adding the line Export http_proxy="http://yourproxy.com:port" in d file /etc/bash.bashrc didn’t work :cry: :!: :!:

Since I had to dig deeper through the whole matter to get it working (again) here, after changes of the proxy, and tight passwords, here is a summary on what is actually going on:

All those username:password@ authentication only do basic (LM) authentication; not NTLMv2. Plus, more and more users have to add ‘special characters’ into their passwords, and then, those special characters are somehow wrongly ‘mapped’ to simple characters (I can’t find the proper reference just now; Dr. Google can help). And, no, escapes don’t help; due to the mapping.

I myself found it quite irritating that my problems here were almost always countered to 99% by those ‘off-the-shelf’ solutions; offered in good faith by the people with weak authentication mechanisms in their organisations. There is no difference between Gnome and KDE, by the way. neither does strong NTLM authentication with their proxy settings. On top of that, KDE (4.4.2) simply disregards its own settings for system-wide proxies. (This is ‘Linux on the desktop’ for you. :( )

i install my ubuntu server 10.4 in virtual machine created by qemu in a debian lenny. after install apt-get does not work using classic parameters like acquire proxy … I found first post creating export http_proxy … and ftp_proxy in /etc/bash.bashrsc was worked. but i believe that ubuntu ‘s people make some assumptions that apt-get acquire does not exists? hummmm. anyway this site unixmen was very usefull for solutions. thank you!!!

I had the same problem and found out, that the way with the apt.conf file in /etc/apt/ works. BUT you have to be careful:

Acquire::http::Proxy "http://proxy.domain/:8080";

The key is the / behind the proxy addr. So if your proxy has the addr "myproxy.mydomain.lan" then it has to look like:

Acquire::http::Proxy "http://myproxy.mydomain.lan/:8080";

Hope that works for you too,

i think ur password contains @ .Replace it with %40 (0×40 = 64 ,the ascii code for ‘@’)

I hope this solves ur problem

#proxy export http_proxy=http://user:password@host:port/export ftp_proxy=http://user:pass@host:disqus :port/
Are you in your right sense ?
There are unix experts everywhere, now days.
Why # ? at the first place ?
And why ftp_proxy is needed ?
Go sleep well before you post.
- http://www.etricks.net NoD
  
  #proxy
  export http_proxy=http://user:password@host:port/
  export ftp_proxy=http://user:password@host:port/
  
  I think that is what he wanted to write.In my opinion, it’s better to write HTTP_PROXY and FTP_PROXY with caps

  I mean seriously, i hate posts that derail and deride. if there are so many unix experts then there would never be any posts about any configuration. furthermore it is obvious the break in the line is represented by a switch, where your argument looks inconcise and n00bish.
  for a unix expert you may need some brushing up, and as for the original post/author – thank you
