Error 111 on adding Repository

[vigs]

Whenever I try to add ANY repository using a command like this:-

sudo add-apt-repository ppa:libreoffice/ppa
I get an error like this:-

Error reading https://launchpad.net/api/1.0/~libreoffice/+archive/ppa: <urlopen error [Errno 111] Connection refused>
What is the reason for this and what is the solution?
Note that I am behind the Institute Proxy server. update's and upgrade's run fine.

dont use sudo, you need to open synaptic repo tab to add:

ppa:libreoffice/ppa

Could you describe in more detail please?
If u want me to go to Synaptic Package Manager->Settings->Repositories->Other SOftware->Add
then shouldn't the line look something like:-
deb http://..... maverick main
