Comment 9 for bug 1847794

As this is a randomly failing and has to due with interface constraints I have reverted commit dbbc280d218fb67cbaf6e1acb30b1549e7c110a5n and have added a 2.6.1 package to ppa:maas-maintainers/experimental3

This will get you on your way while I continue to look into what is causing this regression.
