I was trying to get HDMI to work and broke the video drivers that broke UEFI and I can't get back to where I was and I can't install any updates

I have a ConceptD that has only Ubuntu 22.04 on it I was trying to get HDMI working so I "fooled" with the video drivers. That caused some sort of UEFI error and I rebooted and skipped MOK enrollment out of ignorance. Now I can't move forward or back and the BIOS won't let me edit secure boot or UEFI. That causes all updates to return this error

Please list the exact steps you did to break it.

Did you try turning UEFI Secure Boot off? If using proprietary video drivers you have to create your own key MOK - machine owners key to say that driver is secure. And if changing drivers you must purge before adding a new one.

I first tried to change to a proprietary nvidia driver that prompted a MOK prompt on a restart. I ignored that because I didn't understand the significance. I instead tried to go back to the original drivers which are working. But now I get the following issue constantly. It is impossible to install or remove any software. Please use the package manager "Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first.

I would love to turn UEFI Secure boot off if I could find a way to do that

So I set a UEFI password to boot and then I was able to disable Secure boot. I'm not sure about the update issue yet but progress

After fixing UEFI I ran sudo apt-get install -f followed by sudo apt-get update. Then when the system prompted for a partial update it ran to completion. It is early yet but this seems to solve the problem.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
