This would just restart the landscape services. What's odd is that the
first one, "landscape", timed out.

If you have a deployed cloud and something happened to the juju environment
after that, the dashboard page in Landscape 14.10 would revert to the
install page, as if the cloud was still being installed. This was fixed in
LDS 15.01. If you hit "abort installation", it will most likely destroy the
deployed cloud.

Can you deploy your cloud again using LDS 15.01? At this point, with so
many changes and random errors, it might be the easiest solution. Or do you
have many users and projects created there already?
