You're likely to encounter this while running

sudo apt update && sudo apt upgrade

but you may encounter this more when you upgrade to Zorin 17 (Ubuntu 22.04). For example:

I've also seen other people report this.

The error is likely because the dependencies have been changed. To fix this, run

sudo apt install --only-upgrade

then the name of the package. For example:

sudo apt install --only-upgrade gnome-shell

Hope this helps!
