apt-get does not work with proxy

I have tried changing my proxy settings in a terminal as:

export HTTP_PROXY=


export http_proxy=

but when I try to install a new package or update apt-get, apt-get starts displaying messages from which it seems it is trying to connect to a previously set proxy:

sudo apt-get update  
0% [Connecting to (] [Connecting to (

I have tried setting the proxy via bashrc file but that din work either. As far as I remember was set using GNOME GUI but I don't have access to the GUI right now so I am trying to set it from terminal.

  • you can add proxy in /etc/apt/apt.conf

  • @piyush Will that not only allow apt-get to access the web though..? If he wants to be able to access web with anything else he needs to enter it into /etc/bash.bashrc

    sudo -E apt-get WHATEVER works in my case (given that http_proxy is already exported as an environmental variable). Mar 14, 2015 at 4:03
  • Just a general tip -- when doing these updates, you may need to log out and back in before they start working. That's what I had to do. Jul 1, 2016 at 0:00

Okay just solved it. Adding following line to /etc/apt/apt.conf has solved the problem: Acquire::http::proxy "";

If file does not exist, create it. Do not confuse it with apt.conf.d directory.

    Great. The reason your manual export failed to affect apt-get is because sudo ignores that environment variable by default (i.e. it doesn't pass it on to the command). For one-off runs, you could do sudo env http_proxy= apt-get update. Otherwise, you could configure sudo to allow http_proxy to fall through.

  • also if proxy using authentication then provide the details as sudo env http_proxy=http://<userid>:<password>@ apt-get update Mar 13, 2020 at 5:31

The file:


Is the correct place to specify system-wide environment variables that should be available to all processes. See https://help.ubuntu.com/community/EnvironmentVariables for details. Note that this is not a script file but a configuration file.

If you want this for the specified command only, use (as root):

http_proxy= apt-get update
  • Great! Saved much of my time :)

Edit your:

gedit /etc/profile

Enter the details in this format.

export http_proxy=http://username:password@proxyhost:port/ 
export ftp_proxy=http://username:password@proxyhost:port/

Then run the

sudo apt-get update

That should do it for you.

As stated above you can enter the proxy into apt.conf (Piyush Credit)

  • I have mentioned in my question that I tried setting the proxy via bashrc file and then tried source /etc/bash.bashrc but apt-get is still trying to access the old repository.

    Besides that, /etc/bash.bashrc is the wrong place to set environment variables as it will only affect bash run interactively. Environment variables should be set in /etc/environment or /etc/profile.
