Comment 6 for bug 1603528

Here, we're mixing Horizon from Canonical, with murano-dashboard from Debian. Indeed, murano-dashboard isn't maintained by Canonical (it's synced from Debian), while they do have a separate Horizon package that they maintain by themselves. I haven't dug into the issue, but what I can foresee is that this wont work because these are incompatible. The Horizon package from Debian works differently, and it's done this way to be Debian policy compliant.

So, the only thing I could advise would be to *not* use murano-dashboard with UCA, but with MOS only.
