add-apt-repository

For example, after running this command :

sudo add-apt-repository ppa:tualatrix/ppa

I get the following output :

Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 125, in <module>
    ppa_info = get_ppa_info_from_lp(user, ppa_name)
  File "/usr/lib/python2.7/dist-packages/softwareproperties/ppa.py", line 80, in get_ppa_info_from_lp
    curl.perform()
pycurl.error: (6, "Couldn't resolve host 'launchpad.net'")

Why is it so. I just installed Ubuntu 12.04 LTS. And it works fine. I have updated and installed the system. I have even installed all required packages. But the thing is as soon as I want to install more packages, Like PPA and sort I am not able to.

Till now I have not been able to install any PPA.

I am working behind a proxy.
