Problem adding PPA

[em wai zee]

Hi ... This probably a cliche question. But, here it goes ... I just installed a fresh Ubuntu 12.04 into my lappie. The problem I'm getting while trying to add new PPAs into my Software Centre. Here was one my example while trying adding a PPA!

sudo add-apt-repository ppa:scopes-packagers/ppa

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: (35, 'gnutls_handshake() failed: A TLS packet with unexpected length was received.')

Could anyone here lead me to a set of instructions that will solve this problem immediately! Thanks a lot!

p.s; I've uploaded a screenshot of the problem!
