Comment 55 for bug 186920

@Stefan: you need to use https_proxy as mentioned in https://bugs.edge.launchpad.net/bzr/+bug/186920/comments/50 (the 'comment previous to yours' as Robert mentioned).

> $ env |grep -i proxy
> http_proxy=http://xxx.yyy.zzz.com:8080

> $ strace -e trace=network bzr launchpad-login ensonic
...
> bzr: ERROR: Connection error: curl connection error (couldn't connect to host)
> on https://launchpad.net/~ensonic/%2Bsshkeys

> where "91.189.89.223" is "launchpad-net.nutmeg.canonical.com"

Note the 'on httpS'.
