I'm currently running Zorin 17 Core, and I want to upgrade to Zorin 18 Core. When I use the upgrade tool, it says that I have to fix a repository error. I've followed the link for the instructions to fix it and I've tried to follow the instructions. I can see that there is a broken repository for ProtonVPN, but I'm not sure how to remove it (I've already uninstalled the program).

Can someone help me out here? I'll try to attach pictures of the terminal output from "sudo apt update" and also of the "sources.list" file.
