Unable to Upgrade Zorin OS from 17.3 Core to 17.3 Pro

Installing Zorin OS
1

I recently purchased Zorin OS 17.3 Pro, but I am unable to upgrade from my existing Zorin OS 17.3 Core installation. When I attempt the upgrade, I receive an error message saying that an issue has occurred. I would appreciate any guidance on how to resolve this problem.

Can you please relay the terminal output for:

ls /etc/apt/sources.list.d

cat /etc/apt/sources.list

Let's see if you have a repository added that conflicts in some way.

(This may also be a simple server disconnect issue, usually resolved by waiting a bit before trying again).

I tried several times during the day and the same problem persists.

If I am not mistaken, this provides test builds for GCC, doesn't it? If the GCC conflicts, that would definitely cause a problem.

In Software & Updates, you might switch Download From to "Main Server.

I followed your suggestion and selected the Main Server option in Software & Updates, then saved the changes. However, when I attempted to refresh the updates via Software Updater, I encountered the following errors:

  • Several files in /etc/apt/sources.list.d/ with the .list.save extension are reported as having an invalid file extension.
  • The ElementaryOS repository (packages.element.io) is missing a GPG key, causing signature verification to fail.
  • Due to errors during the update process, it states that previous index files are being used instead.

While a user can install other Distro Repos in order to download software, you must remove that distro's repository or else it may change your Base Software during a system Upgrade - it is a Different Distributions Repository.

I highly recommend removing the extra repositories that affect base system files.
Once done, run in terminal:

sudo apt update && sudo apt dist-upgrade

to see if you can restore your base files to the Zorin OS supplied packages. Then test the Upgrader tool...

EDIT:

This can possibly change your Python version.
