23.04 --> 23.10 Upgrade Problem

I'm attempting to upgrade from Ubuntu 23.04 to 23.10, but it fails every time, likely because of ppa problems. I've attached an image that shows the errors I get when I execute "sudo apt update" prior to running the upgrade. I've tried unchecking the offending ppa in the "Software Sources" app, and I've also commented out the ppa in etc/apt/sources.list. But nothing has worked so far. Any ideas?
