This is caused by a clash between the python-enum package and the python-enum34 package. It has been fixed by porting laditools to python-enum34 in the soon to be released Ubuntu Xenial 16.04.
As a work-around for now, you could remove the python-enum34 package. But this might also remove other applications that you need.
We could probably backport part of the patch used in https://bugs.launchpad.net/ubuntu-seeds/+bug/1498345, but it will probably have to wait until after the Xenial release (unless someone else finds the time).
