I was browsing through the apt folder to try my proxy settings and I was unable to find the apt.conf file in Ubuntu 11.04. Is there any alternative file for it?

Adding proxy settings to 99-synaptic in apt.conf.d does not help as it gets overwritten everytime I restart the system.

The /etc/apt/apt.conf file is still read if it exists. The apt configuration provided by packages is installed as separate files in /etc/apt/apt.conf.d/ so that it can be added and updated independent of any local changes you make in the main configuration file.

So if you have local configuration changes, just create the file.

  • so, lets say, i want a global proxy config that i want to add for cli and software centre (network proxy settings doesnt work for both, a well known fact!), where do i add that? previously adding proxy settings to apt.conf solved all problems!

    Crrate a file in /etc/apt/apt.conf.d/ that has your addition. This has been available for several releases. It is a cleaner way of doing this kind of change.

    As I said, create the apt.conf file and add your settings there. It works identically to previous releases. Apr 12, 2011 at 15:07

Just add the following to /etc/apt/apt.conf and the problem is solved: sudo vi /etc/apt/apt.conf then add this to the first line:

Acquire::http::Proxy "http://proxy_address:8080/";
  • Solved my problem!! Thanks! Fighting it for days.....
