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 must log in or # to comment.
pacman -Syugoes brrrWhen a kernel update requires a change in dependencies, something Proxmox kernels do frequently, apt just quietly “keeps back” the package. It doesn’t fail, it doesn’t break the system, and it doesn’t trigger a rollback. It just waits for me to notice.
This should save a click for hopefully everyone.
Yes obviously, if you do not update the packages then they do not get updated.
If you do not read the output of a command then you will not notuce that.
The standard upgrade command has this behavior though, which is unexpected to people like me and the author. You need a specific flag to tell apt to actually upgrade everything which is not the behavior I expected.
But it is clearly stated in the output that it holds back packages.
Sure in the gigantic wall of text. Also it doesn’t tell you why, or what to do about it. All they’d have to do is say “run dist-upgrade to update these packages.”

It is literally in the summary that gets presented in the last few lines before you have to press Y to continue.
Since you are already overwhelmed by the wall of text, you would probably not read the suggestion antways.
apt dist-upgrade is a necessary change to your process in place of just upgrade.
I may be wrong but I think it’s apt-get dist-upgrade. apt full-upgrade does the same too.
apt-get is now deprecated on Debian and Ubuntu. But otherwise, no notes.
So “apt-dist-upgrade” then? Sorry if obtuse.
apt dist-upgrade. No first dash.Notice it’s
aptnotapt-get. That’s all they were saying.Thanks!
This is specific to Debian and Ubuntu so why not being more specific in the title?
Would apt-get instead of apt have saved you?
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).
