Bug Description

How to reproduce:
  1. open network settings in gnome-control-center
  2. set proxy like the example below:
      * method - manual
      * HTTP Proxy -
      * HTTPS Proxy -
  3. press "Apply system wide"
      - confirm proxy settings are written in /etc/environment and /etc/apt/apt.conf
  4. turn off proxy by set back the Method to "None" and press "Apply system wide" again.
      - confirm proxy settings are gone from /etc/environment and /etc/apt/apt.conf
  5. set proxy again as well as step. 2, then press "Apply system wide" again.

Expected to happen:
  6. proxy settings are written in /etc/environment and /etc/apt/apt.conf

What happened instead:
  6. proxy settings are written in only /etc/environment, then /etc/apt/apt.conf remains as blank.

I can't seem to reproduce this, my apt.conf changes as expected both times. Disregard my previous comment by the way, I found that bug to be a duplicate of one that has already been triaged.

Hi Phil V,
Thank you for checking this bug's reproducibility.
At least for me, I can reproduce this bug on 2 of 2 machines.

Let's wait and see whether others can confirm this bug or not.

I can reproduce it on my machine, but this seems to be a bug in ubuntu-system-service, which is the responsible for writing the proxy settings in /etc/apt/apt.conf. g-c-c only calls it via DBus, so it's clearly a bug there?

I have the same problem. I had created my own (duplicate) bug for this problem at:

I am behind a corporate firewall using a McAfee web gateway, a content-filtering proxy server. Our DNS resolves IP addresses without any proxy settings, but HTTP, HTTPS, and FTP connections cannot be made to addresses beyond the firewall unless we connect through the proxy server. So when executing apt-get, it resolves my mirror's IP address OK, but times-out trying to download the "Packages.gz" file. The only way to make "apt-get" work correctly is to set the "/etc/apt/apt.conf" file, which should be done by gnome-control-center, but it doesn't.

All I can do is write my own script to set "/etc/apt/apt.conf" to use the proxy, and execute it every time I want to run "apt-get" at the office.

Hello Nobuto, or anyone else affected,

Accepted ubuntu-system-service into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See for documentation how to enable and use -proposed. Thank you in advance!

Indeed ubuntu-system-service/oneiric-proposed set proxy for apt on the second time or later.
But it set proxy to apt.conf *and* the all files under apt.conf.d. This is not my desirable behavior.
Please refer attached diff between before and after pressing "Apply system wide".

I think u-s-s already had this bug of writing the same to every file under /etc/apt, but anyway, looking for a fix...
