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.

Problems with Arch upgrade (feddit.uk)

I’ve been using Arch for just over a year on my older Dell laptop, and have been regularly running sudo pacman -Syu but not once have I had a problem or anything break. What am I doing wrong?

every time Ive has a problem it was keyring or bootloader

Same. Except that one time I forgot to charge my laptop and my battery decided it will go to 0% during a kernel update. Charge, Reboot into live iso, arch-chroot, do update. Reboot into normal system, all good. A 5 minute job, but it's the most serious issue I've had to deal with, alongside the keyring issues once which were solved by an Erik Dubois video, a 15-minute fix incuding the video runtime.

Somewhat recently I caused a failed kernel update by accident:

Ran system update in tmux session (local session on desktop). But problem was that tmux itself got also updated, which crashed the tmux session and as a result crashed the kernel update. Only realized it upon the following reboot (which no longer worked).

Your described solution re "live ISO, chroot, run system update once more, reboot" was also what got me out of that situation. So certainly something worth learning for "general troubleshooting" purposes re system updates.
