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 does this happen? 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's and that sort of thing, I am not able to do so.
Until now I have not been able to install any PPA.
I am working behind a proxy.
