From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Having issues with creating Mok keys on Linux Mint. (lemmy.eco.br)

Yesterday I tried to install the latest NVIDIA drivers on my Linux Mint laptop (version 21.3, Cinnamon Edition) and my Driver Manager said that, since i have Secure Boot enabled, I had to create a Mok key for my drivers so I could use them with Secure Boot. So I created a password and restarted my PC. However, I didn't know what to do in the MokManagement screen, so i turned off my PC and then turned it on again to be able to start over. After turning my PC on and off a few times to try a few different buttons thqt I ended up not understanding, I looked up a tutorial and tried to follow it. But when i clicked "Enroll MOK" this time, instead of showing "View Keys", it asked if I wanted to delete my existing keys.

What should I do to get this to work? I turned off my PC after this and switched back to the open source drivers because, again, I had no idea what to do. Did I fuck up my drivers? Can I try to redo the process to make it work? What about the extra keys I created? I'm really confused. Thanks in advance.

I forget what the order of operations is, but you didn't fuck it up. I've deleted the keys and started over before, though I never got secure boot to work for me in the end. Hopefully somebody smarter can provide more insight.

Thank you for your answer. I just remembered I made some Timeshift backups before I tried to switch drivers. If I rollback to the backup will my keys be "overwritten" and I'll be able to try to switch drivers again with no consequences?

Maybe? It depends what Timeshift was monitoring/backing up. In any case, the tool you used to generate the keys I believe has the ability to delete the keys (they're just files on your system). Look up the documentation to be sure. It's been a hot minute since I mucked around with Secure Boot, and it's not strictly required, so I just gave up.

That's about the extent of my secure boot knowledge. I do hope more knowledgeable people have better advice for you!

Will do, thanks!
