Upgrade error from core 16.3 to 17

Hello,

I am using Zorin OS 16.3 core on my notebook and desktop.
But can not be able to upgrade to Zorin OS 17 core on both my notebook and desktop and get the exactly same error when I try to upgrade, which is like below.

Upgrade error log:

Since it seemed a download error, I changed my download server from Korea to main server, but nothing changed. I still get the same error.
What should I do?

Thank you Aravisian. If this is a simple error like due to overwhelmed traffic, then I'll just wait a little bit and try again.

I have upgraded 2 of my 3 machines from z16.3 to z17Core.
the first was during the beta period, an Acer E3-111 laptop, dual core celeron w/8Gb ram and 380Gb hd. it took 2 hours via ethernet connection, has worked well no errors during install. Now this laptop only had Z16.3 on it, no other OS.

The 2nd is a HP laptop quad core amd e2-7110 w/amd radeon r2 graphics, 16Gb ram, 500GB SSD, I began this upgrade a few days ago, it took about an hour and failed, also having issues with the repositories. I was unable to do any fixes as found on the forum so, I downloaded the Z17 core iso image and using balena-etcher to burn created my bootable usb.
I was able to run the install successfully and am pleased with the result. the HP had dual boot previously but, I had already decided to make it a Zorin only machine.

The only thing I needed to migrate over from 16.3 was my favorite background (Aurora). I think this laptop is running faster than when I had 16.3 on it. It used to be dual booted with Win10 home.

I will be restoring my backup for this laptop to bring back my docs.

I will update once I upgrade my desktop. currently it is dual boot with Win10 pro and Z16.3.

Please launch Software & Updates app from the app menu.
In the first tab, ensure that Download From is set to "Main Server" in the drop down menu. Once that is done, close the app and allow it to refresh.
Launch terminal and run

sudo rm -rf /var/lib/apt/lists/*

sudo apt update && sudo apt full-upgrade

The difference between "full-upgrade" and "dist-upgrade /upgrade" is that the "full-upgrade" allows for the overwriting of existing files. The "dist-upgrade" will only upgrade packages which do not require overwriting to be performed.

Once all packages are fully upgraded, Check Your Sources and see if you have any packages installed from third party suppliers that do not have a Jammy repository.
If they lack a Jammy Repository and are no longer being maintained, you won't be able to use that repo on Zorin OS 17, anyway. So remove those packages and repositories.
You can remove a repo by launching Software & Updates then going to the Other software tab, clicking on the repo and then clicking the Remove button on the bottom toolbar.

Once your sources are cleaned up, try running the Zorin Upgrader.

Thanks for your reply. I did all the things above, but unfortunately same result. Also a new error included.

The Chrome source lacks the GPG key for Jammy. I would just remove Chrome and the repository for it, then reinstall Chrome after upgrading. Much easier than trying to untangle it.
