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.

I’m curious, how might
apt upgradebreak something in Proxmox?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” 🤣
Nah, the fun is learning form others mistakes. Thanks for a fun read :}
Not essentially, exactly. One is a deprecated alias for the other.
Which one is which?
I thought full-upgrade replaced dist-upgrade that could make you think you’re upgrading you distro to the next version
But now I’m not sure anymore.
Correct. Full-upgrade is the new term. It’s an alias, though, so using either will accomplish the same thing.
dist-upgrade was used with apt-get
full-upgrade is used for apt
Just don’t use any command in proxmox. Proxmox is designed GUI first. It got an update button in the GUI. Only major releases could need tinkering in the terminal. But even changing repos is now possible in the GUI.
Gets annoying soon if you have more than one host. Easily automated with Ansible
gotta love that GUI, that bombards you with reminders to subscribe to their paid tier repository constantly and won’t let you update…
also, provides no methodology to control when it wants to overwrite a config or when a externally added signable dkms exists and creates a prompt during dkms building.
the gui is nice, but it’s far from perfect…
