It's just about version numbers, as Seth says. The constraint that
should be satisfied is that, if a package is in both series A and series
B and B > A, then version(B, package) >= version(A, package). juju-core
fails this constraint because 15.04 hasn't been upgraded to Juju 1.22.6
but 14.04 LTS has:

  $ rmadison juju-core | egrep 'trusty|vivid'
   juju-core | 1.18.1-0ubuntu1 | trusty/universe | source, amd64, arm64, armhf, i386, powerpc, ppc64el
   juju-core | 1.22.1-0ubuntu1 | vivid/universe | source, amd64, arm64, armhf, i386, powerpc, ppc64el
   juju-core | 1.22.6-0ubuntu1~14.04.1 | trusty-updates/universe | source, amd64, arm64, armhf, i386, powerpc, ppc64el
