Cory's working on this, actually. If we can get it working, we should be able to offer official Caddy packages to all our customers, customized just how they need it to be, so your 'apt upgrade' could upgrade Caddy as well, with just the plugins you want.
> I could have put up with Caddy not being as mature as nginx for some low-volume deployments, and barely put up with the lack of debs, but having to compile my own binaries across the company isn't worth the integrated TLS certs.
Until we have official apt repos, you're welcome to use getcaddy.com which automates builds and installations of Caddy. True, it's not "apt install" but it's pretty close, until we can get apt repos and others available.
