Snappy Ubuntu Core, no Docker or Owncloud in 'store'

I downloaded the image of Snappy Ubuntu Core for the Beaglebone Black, Alpha 2. When I now try to install Docker or Owncloud it cannot be found. Nor are the apps/framework available through the WebDM 'app store'. Numerous guides online refer to both these applications as being available already, some from January some from all way back in December.

I should add that I am using the latest available version of Ubuntu Core (there are no updates when checking - updating has worked in the past, so that is not the issue) with the build number 2. Which is odd, often in guides people are using 1XX etc. I am also using the 'channel' (which I assume is the 'repository') ubuntu-core/devel. Also, there are other apps available (5-6 meaningless example apps) but not Docker or Owncloud.

Does the precompiled image for the Beaglebone have a different repository than the regular Snappy Ubuntu Core, or have they been pulled?

EDIT: I was looking for information as to what happened to the packages on the armhf platform

At least the 15.04 release (dated 13-Nov-2015) has docker available if you do a 'snappy search docker'.

ownCloud has two packages: a snappy package and a docker package, but the former is not available for BeagleBone Black.

And after you install docker, you can find ownCloud as a docker package. It's interesting that it doesn't show up before installing docker.

The packages are still available, but only for the amd64 architecture:
