Not compatible with servers using Ubuntu Stretch

After much banging my head against a wall trying to figure out why this plugin keeps giving me a 500 internal server error within seconds of hitting import, it turns out it’s not compatible with Stretch. I have only reliably been able to get it to work on Trusty so far. It seems this is a dead plugin, but since it’s WordPress official, I really hope there’s going to be an update here soon.
