Comment 15 for bug 1761813

FWIW, I found a really old IRC log (1.4 times) talking about this similar
issue. Not saying it’s related or the same, but just bringing it up in case
this could lead somewhere.

[08:33] <gmb> rvba: That could work. We can't specify https_proxy *at
all* for simplestreams, or else it breaks.
[08:34] <gmb> If you give it an http url by accident (I just did) you get
[08:34] <gmb> simplestreams.util.SignatureMissingException: No signature found!
