Module not registered: dns.providers.cloudflare

[Merc]

1. The problem I’m having:

I am trying to enable the Cloudflare DNS module but constantly get a ‘module not registered’ error.

2. Error messages and/or full log output:

merc@caddy:~$ sudo caddy reload --config /etc/caddy/Caddyfile
2023/05/11 07:30:52.565	INFO	using provided configuration	{"config_file": "/etc/caddy/Caddyfile", "config_adapter": ""}
Error: adapting config using caddyfile: parsing caddyfile tokens for 'acme_dns': /etc/caddy/Caddyfile:2 - Error during parsing: getting module named 'dns.providers.cloudflare': module not registered: dns.providers.cloudflare

3. Caddy version:

v2.6.4

4. How I installed and ran Caddy:

Installed following recommended sudo apt install sudo method, then replaced caddy binary in both /bin and /usr/bin with downloaded version after selection amd64 arch/cloudflare module from download page. Then rebooted.

a. System environment:

Ubuntu 22 x86_64

b. Command:

Caddy is started automatically by service created with apt install. But error appears each time I run:

Now you have the answer why the message is in the log .
The solution is to make again the download on Download Caddy or build your own binary with xcaddy

[Merc]

So you are saying that the download page doesn’t work as intended?

[al-caddyserver (Aleks)]

Well no just repeat the message from the download page.

Due to multiple outstanding bugs in the go command, we are aware that some downloads may hang or fail. In the meantime, you can download Caddy from the latest release on GitHub, or use xcaddy for custom builds. (Remember, this download page comes with no guarantees or SLAs.) Sorry for the inconvenience.

I would try to download as long as the module is in the binary or build my own based on xcaddy.

[Merc]

Thanks for your suggestions @al-caddyserver. It seems the curl download direct to the server wasn’t grabbing the correct version. When I did it manually on my Mac and SCP’ed it to the server the module now shows.
