How to get and install OwnTone

You can compile and run OwnTone on pretty much any Linux- or BSD-platform. The instructions are here.

Apt repositories, images and precompiled binaries are available for some platforms. These can save you some work and make it easier to stay up to date:

Platform	How to get
RPi w/Raspberry Pi OS	Add OwnTone repository to apt sources, see: OwnTone server (iTunes server) - Raspberry Pi Forums
Debian/Ubuntu amd64	Download .deb as artifact from Github workflow (requires that you are logged in)
OpenWrt	Run opkg install libwebsockets-full owntone
Docker	See linuxserver/docker-daapd

OwnTone is not in the official Debian repositories due to lack of Debian maintainer and Debian policy difficulties concerning the web UI, see this issue.
