dnf-remove example crashes

[anaselli]

I removed the line 83: https://github.com/timlau/dnf-apiex/blob/master/dnf-remove.py#L83 since it seems that property is not accessible any more in that way at least, but the second transaction, e.g. the remove package one, fails with a core dump. So no backtrace is available. No problems if we install two packages or remove to packages, the problem is in mixing installing and removing

self.goal_parameters.allow_uninstall = True

allow_erasing option is now in cli.demands.allow_erasing.

Have you run it under the root?

[anaselli]

yes as root, packages are installed correctly, is the second transaction that crashes the one that should remove them. Do you think is the cli.demands.allow_erasing property that makes that working?
