Upgrade Core 17 to 18 error messages unsure what to do

Installing Zorin OS
1

Hello,

I am trying to upgrade an iMac9,1 20 inch (Early 2009) from Zorin Core 17 to Core 18. I updated all the softwares and packages before starting. Started the upgrade process. Then the software updater showed up Saying "Not all updates can be installed". I pressed "Continue" then got an error about "The package system is broken", I tried to press "ok" but then everything got stuck.
Now, The upgrader is asking to restart but I am unsure what to do, I am worried that now the OS is broken.
Any advise would be greatly appreciated.

Did you already run

sudo apt install -f

?
Then check if everything is okay with

sudo apt update && sudo apt upgrade

Also disable or remove third party repositories before the upgrade.

Then try the upgrade again.

Do You have added any Third-Party Repo's? If yes, delete them all. You can add them later again. Then type in the Terminal sudo apt update && sudo apt upgrade and when that is done type sudo apt install -f

Thank you both.
No, I don’t have any third party repos

I ran

sudo apt update && sudo apt upgrade

This upgraded:

zorin-os-default-settings and zorin-os-printer-test-page

Then ran

sudo apt install -f

This says:

0 to upgrade, 0 newly install, 0 to remove and 0 to upgrade

So i guess it’s safe to restart?

I would think yes. But better safe Your Data for Worst Case first and keep a Bootstick with Zorin prepared.

Just adding resolution here since the post was split into a new topic
Thanks a lot, seems to have worked. I seems to be on Zorin 18 Core now. I guess I should have probably left the Software updater window alone and not press anything there.
