But there are two that may cause problems:
brave-browser-release.list zorinos-ubuntu-drivers-jammy.list
mozilla.list zorinos-ubuntu-patches-jammy.list
I would remove those two and try the upgrader then.
Brave can be finicky.
The way I would do this is just move the repository files to a spot where they cannot be seen by the system, in case you want to restore them (Say the upgrader still fails, and you want to continue using your OS and it get all update notifications).
Run Files as admin ("Files" is Nautilus File Manager):
nautilus admin:///
Navigate to /etc/apt/sources.list.d and create a new folder named source.d-back
Drag and drop the Brave and the Mozilla repo into that folder.
In terminal run
sudo apt update && sudo apt upgrade
Then test the Zorin Upgrader tool.
You can later drag and drop them out of that folder and back into parent folder sources.list.d to restore them if the upgrader does not upgrade you to Zorin OS 18.
No, that is software that Nautilus uses to pre-cache your frequently used files in order to speed up loading time.
I think the package name is tracker-miner-fs.
To restore the repo, if you are Now on Zorin OS 18
I recommend Adding the Noble repositories for your Browser. The old ones you moved are for Jammy, not Noble.
For the record, that fix worked on my HP EliteDesk machine too. Just the Brave and Mozilla repositories needed removed for the upgrade to proceed normally.
