I've done some testing of this and the test case, specifically using 'export http_proxy', doesn't seem to do anything. You could use 'export http_proxy=localhost:1245' and because you are behind a proxy server you would receive the same results. While for me it just works. We need to the right way to set the proxy for python or urllib2.

[Brian Murray (brian-murray)]

It looks like

proxy_support = urllib2.ProxyHandler({"http" : "http://ahad-haam:3128"})

might work.

I tried this. It's not working...

Ok, I'm far away from being a network and proxy expert, but my first guess is you need to use an https proxy, since launchpad is using https for all requests. Can you please try this:
$ export https_proxy=http://<host>:<port>
$ bugnumbers -p bughelper

and check the output (I think this will return an exception as py-lp-bugs really is not supporting proxies, but this should not be a 'connection refused' error)

This is not working... :(

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect 194097 and any other logs that are relevant for this particular issue.
