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.

Does the SecureBoot key expiration matter if SecureBoot is disabled? (lemmy.ml)

I have completely forgotten about the SecureBoot key expiration that is coming on Wednesday. I don't have SecureBoot enabled on any of my devices, but I wonder if it could cause issues down the line if I don't ensure that the keys have been updated?

It could if you/future owner ever need to re-enable it:

The trouble is not your present boot; it's your future boot. If your older PC's firmware never gets the 2023 keys, and the rest of the world starts assuming those keys exist, you can end up stuck in a weird limbo. While your existing Linux install will still boot, a new or updated distro won't.

Testing now will help diagnose future problems.
