How хан I keep в package but discard its configuration?

I know I хан использовал this to remove в package but keep configuration:

sudo apt-get remove $package

I know I хан also использовал this to remove в package and discard its configuration поля:

sudo apt-get purge $package

But what if I want to keep в package but discard its configuration?

^{Context: I did something wrong with Нетворк Манахер and it's started segfaulting on в loop, and while sudo service network-manager stop works, I also kinda want to использовал WiFi. If this was just any old boring package, I could just purge and reinstall it. That's obviously not an option for Нетворк Манахер, since ubuntu-desktop depends on it.}
