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 "";
8

Unattended Upgrades only checks and updates programs in repos it knows about. As you found out, you'll need to add the custom repository to the Origins pattern in 50unattended-upgrades.

You can find a list of all repositories and their data using apt policy

Here are the custom repositories I have on one of my servers:

 500 https://repo.zabbix.com/zabbix/7.0/debian bookworm/main all Packages
     release v=12,o=Zabbix,a=zabbix,n=bookworm,l=zabbix,c=main,b=all
     origin repo.zabbix.com
 500 https://repo.zabbix.com/zabbix/7.0/debian bookworm/main amd64 Packages
     release v=12,o=Zabbix,a=zabbix,n=bookworm,l=zabbix,c=main,b=amd64
     origin repo.zabbix.com
 500 https://pkgs.tailscale.com/stable/debian bookworm/main all Packages
     release o=Tailscale,n=bookworm,l=Tailscale,c=main,b=all
     origin pkgs.tailscale.com
 500 https://pkgs.tailscale.com/stable/debian bookworm/main amd64 Packages
     release o=Tailscale,n=bookworm,l=Tailscale,c=main,b=amd64
     origin pkgs.tailscale.com
 500 https://deb.nodesource.com/node_20.x nodistro/main amd64 Packages
     release o=. nodistro,a=nodistro,n=nodistro,l=. nodistro,c=main,b=amd64
     origin deb.nodesource.com

Look at the line starting with release and search for a combination that uniquely identifies the Caddy repository.
The output above is using the short form keywords, while the examples in 50unattended-upgrades use the long form. It's fine to use either.
One special case is the site keyword. This is the URL coming after origin in the output above and might be confusing.

Keywords

//   a,archive,suite (eg, "stable")
//   c,component     (eg, "main", "contrib", "non-free")
//   l,label         (eg, "Debian", "Debian-Security")
//   o,origin        (eg, "Debian", "Unofficial Multimedia Packages")
//   n,codename      (eg, "jessie", "jessie-updates")
//     site          (eg, "http.debian.net")

Based on the apt policy output above, here's what I use to enable automatic updates for these repositories.
Using origin and codename follows the standard Debian repos and I'd recommend using that if possible.
Node doesn't provide a reasonable repo file, so I had to set site based on the URL behind origin in apt policy

"site=deb.nodesource.com"; //Nodesource repository
"origin=Zabbix,codename=${distro_codename}"; //Zabbix Agent repository
"origin=Tailscale,codename=${distro_codename}"; //Tailscale repository

Firstly thank you so much for explaing this for me.

"origin=Zabbix,codename=${distro_codename}"; //Zabbix Agent repository

I tried using this as a template for caddy

 500 https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version/main arm64 Packages
     release o=cloudsmith/caddy/stable,a=any-version,n=any-version,l=source=none,c=main,b=arm64
     origin dl.cloudsmith.io

I assume origin is:

o=cloudsmith/caddy/stable

When adding this rule

"origin=cloudsmith/caddy/stable,codename=${distro_codename}"; //Caddy repository

I get this error

Unable to parse Unattended-Upgrade::Allowed-Origins.
An error occurred: not enough values to unpack (expected 2, got 1)
Traceback (most recent call last):

https://pastebin.com/raw/7gtkRw7c

When changing the syntax to:

"cloudsmith/caddy/stable:${distro_codename}"; // Caddy

The error goes away.

Any ideas?

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";

"origin=cloudsmith/caddy/stable";

Huh, I guess Ubuntu patched Unattended Upgrades to change the config format.
Try "cloudsmith/caddy/stable:any-version";

Not exactly what you're asking for, but I'll share what I do. I'm using SaltStack to do config management and one of my salt states brings all packages up to date. This is done every 24 hours. I'm not suggesting you install SaltStack just for that but rather pointing out for people who use config management tools that those might be able to handle unattended upgrades.
