Can't uninstall gnupg2 to upgrade to SF Kvarken

when trying to upgrade to Kvarken, Sailfish tells me that I first need to uninstall gnupg2.

When trying to remove that package with pkcon remove gnupg2, pkcon tells me that removing that package would crash my system and exists.

So, why would removing gnupg2 crash my system and how can I work around that situation to get the upgrade installed?
