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.

Yeah, apt is an unwieldy piece of shit.

is this specific to apt? dnf or pacman dont suffer from this?

[-] thurstylark@lemmy.today 1 points 8 hours ago

I don't know about dnf, but pacman doesn't do this by default. The only way to hold back packages is by writing it in the configuration.

I've not come across this with my non Debian based systems. Only use Debian for servers because it's so stable, Arch and Fedora everywhere else!

I don't know for certain but this seems pretty apt specific.

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.
