Comment 4 for bug 1473091

It seems like all the package files are already on launchpadlibrarian.net through https, eg https://launchpad.net/~fnu/+archive/ubuntu/main-fnu/+files/libcurl3_7.36.0-1fnu0~trusty_amd64.deb which redirects to https://launchpadlibrarian.net/173431189/libcurl3_7.36.0-1fnu0~trusty_amd64.deb

So isn't it just a case of changing the urls in the relevant file in /etc/apt/sources.list.d/ ?
