4. Error messages and/or full log output:

Specifically it is this:

Looked at caddy.service file, which appears to be HTML:

/etc/systemd/system$ cat caddy.service

Huh, that’s very strange. I have no idea how that could’ve happened. I took a look at the .deb that’s hosted on gemfury and the contents look right. The .deb install hooks don’t do any requests to github either, so I don’t understand…

Your caddy.service file looks like this now, right?

github.com

caddyserver/dist/blob/master/init/caddy.service

# caddy.service
#
# For using Caddy with a config file.
#
# Make sure the ExecStart and ExecReload commands are correct
# for your installation.
#
# See https://caddyserver.com/docs/install for instructions.
#
# WARNING: This service does not use the --resume flag, so if you
# use the API to make changes, they will be overwritten by the
# Caddyfile next time the service is restarted. If you intend to
# use Caddy's API to configure it, add the --resume flag to the
# `caddy run` command or use the caddy-api.service file instead.

Okay I have a hunch (shoutout to @elcore for pointing me in the right direction here).

Is it possible that you tried to install the Caddy service manually before? Maybe you used curl to grab the service file from github, but you actually downloaded the github HTML instead of the raw service file?

This is what I think might’ve happened:

Some time ago, you did some curl or wget command to pull down the service file directly from github, not realizing it was the full HTML page from github rather than the raw contents
You set up the gemfury repo and installed the caddy package
The .deb install process (the standard system behaviour) noticed there was already a caddy.service on disk, so it didn’t overwrite the file and just left it as-is.
The post-install hook of the .deb (which we wrote, which comes with the .deb) then tries to enable the service, but it fails because it’s an HTML document
You then uninstall the package, which involves a cleanup step which should remove the caddy.service file because it’s no longer needed
You then install once again, which finally does write the correct caddy.service file to disk.

Does that sound about right?

Jeff_Galbraith · August 8, 2020, 1:58pm

Yes, I think you are exactly right. Good sleuthing!
I investigated Caddy some time ago and now revisiting to do our actual implementation.
