I am afraid you got a cause and effect wrong.
The cause of the problem is secure boot which manifests itself as a problem in VirtualBox update.
Even we could help you to solve the current VirtualBox issue, you will hit another roadblock eventually when such update comes to your system next time.
OP can try.
But I do not think it would help.
I first thought the problem was incomplete installation but then I found out that the system got secure boot enabled.
I find it hard to make any sense of that though because I have been updating my Zorin 16 Pro system everyday since 17th August and everything has been fine.....with UEFI Secure Boot enabled.....up to now and this VirtualBox update.
So if I remove the VirtualBox update my immediate problem is resolved....no?
You should learn how to consolidate your postings into one. It is not a Twitter and longer meaningful postings are more appreciated than short meaningless ones.
Happy to receive anyone's help and appreciate it too. Not happy to turn off UEFI Secure Boot on a dual boot system with Win 10.
Neither Win 10 nor UEFI Secure Boot have cause the issue, it's the update to VirtualBox from what I can tell and I just need to remove it.
I can promise you I'm not trying to annoy anyone, it would be counterproductive especially as I intend to be a committed Zorin user and will likely be asking for further guidance in the coming months. You especially Aravisian helped me a couple of weeks ago with the Dell problem.
Kedric, I'll try that but is it OK for me to kill off the Terminal which still has the process running from before? It's waiting for me to say OK to this:
I understand your point of view. However, the trouble is that you also refuse to configure it. Do you see the issue here? You won't turn it off, but refuse to configure it, creating your own quandary.
This is what we are trying to explain: The virtualbox issue is a symptom not a cause.
Mate, thank you, I'm definitely on the same page about being careful, hence my reason for posting and asking for help. The enrolling an MOK worried me because I don't know the implications and it's also a third party driver and all a bit above my head.
Anyway, I appreciate your post and good luck Wisconsin
In which case, you can just close the window as Tom suggested. This will bring us back to the original problem.
First, you need to be able to successfully run dpkg --configure .
It's a bit of a loop and there is no way to say 'Not OK' and I certainly don't want to create a private MOK, especially for something which I'm actually trying to uninstall.
