Why the Old Methods Fail
If you search for “install Sonarr on Linux,” you’ll find plenty of guides telling you to add a repo, install Mono, and call it a day. On Raspbian, that advice is outdated and mostly broken.
I hit this wall myself. The traditional Sonarr install steps that work on Ubuntu or Debian-based servers either fail outright or leave you with a non-functional service on Raspberry Pi. This article documents what actually works on Raspbian today.
If Linux still feels unfamiliar, I strongly recommend reading A Beginner’s Guide to Linux first. It explains distributions, package managers, and basic commands used throughout this guide.
What This Post Is About
This post covers:
- Why native Sonarr installs fail on Raspbian
- Why Docker is the correct solution
- A working, repeatable Docker-based Sonarr install
Why the Traditional Sonarr Install Does Not Work on Raspbian
The usual instructions rely on one of these assumptions:
- Mono packages are available and maintained
- Sonarr’s APT repository supports your architecture
- You’re running Ubuntu or full Debian
On Raspbian (especially 32-bit):
- Mono support is inconsistent or deprecated
- Sonarr v4 is .NET-based, not Mono-based
- Official repos do not reliably support ARMhf
The result is broken dependencies, services that won’t start, or Sonarr crashing on launch. You can sometimes brute-force it, but it’s fragile and not worth maintaining.
The Correct Approach: Run Sonarr in Docker
Docker avoids all of these problems:
- No dependency hell
- Architecture-compatible images
- Easy updates
- Consistent behavior across systems
This is how I run Sonarr on my Raspberry Pi 4, and it’s been stable.
Prerequisites
- Raspberry Pi running Raspbian
- SSH access
- Docker installed
- Docker Compose installed
If Docker is not installed yet:
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker pi
sudo reboot
Install Docker Compose:
sudo apt install docker-compose -y
Create the Sonarr Docker Configuration
Create a directory for your media stack:
mkdir -p ~/docker/sonarr
cd ~/docker/sonarr
Create a docker-compose.yml file:
version: "3.8"
services:
sonarr:
image: lscr.io/linuxserver/sonarr:latest
container_name: sonarr
environment:
- PUID=1000
- PGID=1000
- TZ=America/Winnipeg
volumes:
- ./config:/config
- /mnt/media/TV:/tv
- /mnt/downloads:/downloads
ports:
- 8989:8989
restart: unless-stopped
Adjust paths to match your system. The container does not care where the files live — only that the paths are consistent.
Start Sonarr
docker-compose up -d
After a minute or two, open your browser and go to:
http://<raspberry-pi-ip>:8989
What Worked
- Docker image pulled cleanly on ARM
- Sonarr started without errors
- Updates are one command
- No dependency breakage
What Didn’t
- Native APT installs
- Old Mono-based instructions
- Trying to “make it work” manually
Lessons Learned
- Raspbian is not Ubuntu — treat it differently
- Docker is not optional anymore for ARM apps
- If a guide mentions Mono, it’s outdated
Wrap-Up
If you’re running Sonarr on Raspbian, stop fighting the OS. Docker is the clean, stable solution, and once it’s running, you’ll never want to install it any other way.
Summary
- Traditional Sonarr installs fail on Raspbian
- Docker avoids architecture and dependency issues
- The LinuxServer.io image works reliably on Raspberry Pi

Question for the Reader
Are you running Sonarr directly on bare metal, or have you moved everything into Docker? What broke first?
