Zorin OS Upgrader cannot check the system requirements

Installing Zorin OS
1

I want to upgrade my OS from Zorin 16 to 17 using the upgrade app, but it tells me there's an error when checking the system requirements.

The content of the error report indicates it's an issue of duplicated files or modified files. I have tried using sudo apt --fix-broken install, sudo apt autoremove, and going through sudo nano to find duplicates of files (I did not find duplicates). This leads me to think it's either because I unsuccessfully tried to download Librewolf, or because I dual boot with windows 10. What can I do to fix or upgrade my computer?

The following is the crash report copied and pasted:

You can just remove the broken Librewolf repository.

To resolve this, remove the duplicate entries.

Welcome to the Forum!

Okay, the first Thing are multiple Configurations. To solve that You can open the Terminal and type:

sudo nano /etc/apt/sources.list.d/zorin.list

There You go in Line 13 and set at the Beginning of the Line a # and the type ctrl+o, then Enter and then ctrl+x. With ctrl+o You save the Changes, with Enter You confirm and with ctrl+x You close it.

The Problem with this LibreWolf Repo is that there is no GPG Key for it. The Key is a Security Thing that verified the Repo. You could delete the Repo and add them again when You did the Upgrade. To delete it go to Software & Updates and there to the Other Software Tab and look for the Entry and delete it.
