Comment 1 for bug 1483196

this is known, the goal is to drop the dependency on python-parted.
we did not implement a work around as we're getting rid of it soon.

wily works, but trusty was tricky as the curtin launcher picks between available pythons, and in trusty:
  python3-parted is not packaged
  python-yaml (python2) is not available,

so the bin/curtin launcher doesn't find either one as suitable.

we could work around it, but we hope to fix it by dropping parted soon.
