Thinking about doing an upgrade soon to Zorin OS 18 Pro from 17 Pro, but I wasn't sure if upgrading would be a problem considering I have secure boot enabled and OS 17 installed via UEFI. Should I just do a clean install like I usually do?
No, you should not need to... But I do not use Secure Boot (I do not dual Boot with Windows OS), so I cannot speak from experience.
The MOK Keys are to enroll the user - but the certificates are not stored on the Zorin OS build.
Worst case scenario, you might have to re-enroll MOK. Annoying, not dangerous.
You can try the upgrade to see if everything works well, and if you're not satisfied with the result, you can make a fresh install.
Personally, I'll do a clean install when something isn’t working as well as I’d like and I can’t fix it. As long as everything is working well, I’ll stick with it, because a clean install always involves a lot of work.
Sorry, another thing that's not at all related to this topic. What in the world is this upgrade discount I read about? It's talked about in the bottom of the OS Pro page and says...
Future major versions — such as Zorin OS 19 Pro — will need to be purchased separately when they will be released in the future. However, you'll be able to upgrade to future major versions at a discount.
Where the hell can I get this discount because I've always paid full price for every new release. Not that I don't mind, it supports the developers after all, but XD
I believe there is a section that you enter the code from your previous Pro Purchase during the upgrade process.
Doing so should then apply the discount to the Next Pro release you are upgrading to.
In this Case, I would think disabling Secure Boot should be fine and avoiding Issues. I mean, yes. It is called ''Secure Boot''. But at the End Microsoft decides what is secure and what not.
