libpango1.0-0 package missing in focal

18.04 has libpango1.0-0 (potentially as a transitional package)
20.04 doesn't appear to have it.

Perhaps libpango1.0-0 could be added to 20.04 as a transitional package?

This issue presented itself when installing Minecraft.deb on 20.04

minecraft-launcher does function on 20.04, but is removed during an "apt --fix-broken install"
