Assuming you installed caddy via Debian, Ubuntu, Raspbian method

https://caddyserver.com/docs/install#debian-ubuntu-raspbian

add "cloudsmith/caddy/stable:any-version"; to /etc/apt/apt.conf.d/50unattended-upgrades

Example:

// Automatically upgrade packages from these (origin:archive) pairs
//
// Note that in Ubuntu security updates may pull in new dependencies
// from non-security sources (e.g. chromium). By allowing the release
// pocket these get automatically pulled in.
Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        // Extended Security Maintenance; doesn't necessarily exist for
        // every release and this system may not have it installed, but if
        // available, the policy for updates is such that unattended-upgrades
        // should also install from here by default.
        "${distro_id}ESMApps:${distro_codename}-apps-security";
        "${distro_id}ESM:${distro_codename}-infra-security";
        "${distro_id}:${distro_codename}-updates";
//      "${distro_id}:${distro_codename}-proposed";
//      "${distro_id}:${distro_codename}-backports";
        "cloudsmith/caddy/stable:any-version";
};

Origional post:

Hi guys anyone know how to use un attended upgrades with caddy.

I have ubuntu server 22.0.4.

The part that stumps me is caddy uses a external repository cloud Smith making ot difficult to setup.

I installed caddy via Debian, Ubuntu, Raspbian

https://caddyserver.com/docs/install#debian-ubuntu-raspbian

The closest example I could find to unattended upgrades with a external repo was this example using docker.

/etc/apt/apt.conf.d/50unattended-upgrades

"Docker:${distro_codename}";

https://blog.coffeebeans.at/archives/1299

I’m not sure if it’s as simple as

/etc/apt/apt.conf.d/50unattended-upgrades

"Caddy:${distro_codename}";

Edit:

One more question affect would adding

APT::Unattended-Upgrade::Package-Blacklist "";

/etc/apt/apt.conf.d/20auto-upgrades

have?

Edit2:

I just removed this I only found this from google gemini (which probably isn’t the best source of info)

APT::Unattended-Upgrade::Package-Blacklist "";

    You’re right with the origin. codename or n in short form is any-version. ${distro_codename} won’t match that, as it contains the codename for your distro release, like bookworm for Debian 12.
    With any-version the repo owner’s basically saying you can install this regardless of your distro version or they handle it on their end somehow.

    Try just using the origin instead, like this.

    "origin=cloudsmith/caddy/stable";
