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.
You’re not supposed to run apt upgrade in Proxmox at all, it may even break your system. Use dist-upgrade.

dist-upgrade and full-upgrade are essentially the same command but yeah, I won’t be using apt upgrade again in the future! Like I said in my post, the joys of being self taught is that you learn by my making mistakes and that’s part of the “fun” 🤣
Not essentially, exactly. One is a deprecated alias for the other.
