Comment 11 for bug 1536487

I backported this and tried my tests again, but this alone isn't sufficient to get the T->X->T working (which is effectively 2.0->2.5->2.0).
Wily (2.4) is already out of service, so setting this to won't fix.

Thanks for your guidance, but that now properly known I'll set the Xenial task to won't fix for now.
