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.

No, apt isn’t just a rename. apt upgrade largely replaces apt-get upgrade, but it’s a bit more aggressive: it may install new packages if required as dependencies (it still won’t remove packages). If an upgrade needs to remove packages to resolve dependencies, use apt full-upgrade (same as apt-get dist-upgrade).
