As near as I can tell, 'juju-website' is only the theme, though, so I
couldn't actually fix the page itself. Hopefully Jorge can let us know
if there is something we can do to help him out.

Well, it is unclear if we will be able to remove this for HP Cloud
since we don't publish the images there ourselves.
So there isn't something like cloud-images.ubuntu.com to query to find
out what the "current" images are for a given series on a given region.

We might end listing the images and trying to pull out the best match,
but that will be making assumptions about how HP puts stuff into the
'Name' field, which looks to be much more about human-readable rather
than machine processable.

You might try running "juju --debug <command>" which gives a bit more
context as to what is going on.

Object storage activation isn't something we've had to do ourselves,
so getting some context so we can give cleaner errors would be very
helpful.

We should update the documentation to point at userpass, which I added
to the above bug on juju-website.

You should also feel free to ask for help on #juju-dev in
irc.freenode.net. That might be a better way to get interactive help.
