DietPi OS APT update warnings

Troubleshooting
1

I am running DietPi OS (v10.0.1) on a Raspberry Pi 4 (4GB) as a headless server for various LAN services (Jellyfin, Samba, Pi-hole, Unbound, Tailscale), and when updating, I see the following warnings:

Warning: http://archive.raspberrypi.org/debian/dists/bullseye/InRelease: Policy will reject signature within a year, see --audit for details

Warning: http://archive.raspberrypi.org/debian/dists/trixie/InRelease: Policy will reject signature within a year, see --audit for details

Although it tells me to “see audit for details,” I do not know what that means, nor where to go to see the audit.

Can anyone explain what these warnings mean, and how to resolve them? Thank you in advance!

This comes from APT’s signature verification system.

In short:

  • The Raspberry Pi archive signing key used for
    archive.raspberrypi.org
    is approaching an expiration or weak-policy threshold
  • APT is warning you in advance that:
    • Updates are still accepted now
    • But future APT versions will refuse that signature unless it’s refreshed

This is a heads-up, not a failure.

apt update --audit
