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.

Linux and Secure Boot certificate expiration (lwn.net)

submitted 1 week ago by HaraldvonBlauzahn@feddit.org to c/linux@lemmy.ml

Linux users who have Secure Boot enabled on their systems knowingly or unknowingly rely on a key from Microsoft that is set to expire in September. After that point, Microsoft will no longer use that key to sign the shim first-stage UEFI bootloader that is used by Linux distributions to boot the kernel with Secure Boot. But the replacement key, which has been available since 2023, may not be installed on many systems; worse yet, it may require the hardware vendor to issue an update for the system firmware, which may or may not happen. It seems that the vast majority of systems will not be lost in the shuffle, but it may require extra work from distributors and users.

I think this already bites people, it has started, it's not in September but now?: https://x.com/rogerioperdiz/status/1946873449537798582

I just tried to distro-hop and found my BIOS had been locked with a password. Assuming I didn't set a password that I subsequently forgot (and that isn't one of the many I have memorized), I figured this might have something to do with the age of the laptop (I have a HP 4540s). If certificate expiration is already affecting people then this might be it.

EDIT: I just forgot I set a password, and it took me 2 days to realize that I was stupid enough to have set the password that I used for everything when I was 12 years old.

How did you bypass the password?

Not OP, but BIOSes often give you a specific error code after a few wrong password attempts. You can put the code in here to recover the password: https://bios-pw.org/

I didn't. And apparently you can't without trying to short-circuit the motherboard. I just assumed, and assumed wrong.
