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.

I’ve been running my home lab since 2021 and honestly thought my update routine was solid: apt update && apt upgrade, reboot, job done.

Turns out I was wrong. I was checking CVE‑2026‑31431 (Copy Fail) this morning and realised that despite my “successful” updates, I was still running a vulnerable kernel from March.

I’ve had to rethink how I handle host updates. If you’re relying on a standard upgrade and a reboot to keep Proxmox or Debian hosts safe, you might want to check if yours is lying to you as well.

I've been running Debian since 2007 and never understood the point of apt upgrade .
When I update, I want the updated version for everything on my system.
I don't want to arbitrarily hold back packages just because a dependency changed. I'll decide for myself if that's an issue in my deployment. And Debian is generally very good at keeping everything running exactly the same way between releases.

I pin the release by name (not "stable") and then apt dist-upgrade always.

I've always been doing apt dist-upgrade. What's the difference between dist-upgrade and full-upgrade?

none.
