App not running

I tried installing the Umbrel app, but after installation, it had issues and stopped running. I then deleted all related files via the terminal. However, the App Store did not recognize this and still shows the app as ‘Not Running,’ preventing me from reinstalling it.

Is there a specific file where I can remove installation records so the App Store no longer thinks the app is installed? Or are there other solutions to fix this?

Let’s make sure you’re properly sized, and then if you aren’t, maybe consider starting over?

To run Umbrel on a Raspberry Pi without encountering future problems, you’ll want hardware that ensures smooth performance, reliability, and scalability. Umbrel is designed to be lightweight, but its demands increase if you run a Bitcoin node, Lightning Network, or additional apps from its app store (e.g., Nextcloud, Jellyfin). Below are recommended hardware specifications for a Raspberry Pi setup, tailored to eliminate common issues like slow syncing, storage shortages, overheating, or SD card corruption.

Recommended Hardware Specs

1. Raspberry Pi Model

  • Model: Raspberry Pi 4 (preferred) or Raspberry Pi 5
    • Why: The Pi 4 is officially supported by umbrelOS and widely tested. The Pi 5 offers better performance (faster CPU, improved I/O) and future-proofing, though full Umbrel support for Pi 5 is still maturing as of April 6, 2025.
    • Avoid: Pi 3 or earlier models lack the power and memory for Umbrel’s full feature set (e.g., Bitcoin node syncing).
  • RAM: 8GB
    • Why: 4GB works for basic setups (Bitcoin node only), but 8GB ensures headroom for multiple apps, faster blockchain syncing, and reduced strain during peak loads. The initial Bitcoin blockchain download (IBD) is CPU- and memory-intensive, and 8GB prevents bottlenecks.

2. Storage

  • MicroSD Card: 32GB (minimum), Class 10, High-Endurance (e.g., SanDisk Extreme or Samsung PRO Endurance)
    • Why: The microSD card hosts the OS (umbrelOS). A high-quality, high-endurance card prevents corruption from frequent writes (a common failure point). 32GB provides ample space for OS updates and logs.
    • Avoid: Cheap, low-end SD cards—they corrupt easily under Umbrel’s constant use.
  • External Storage: 2TB SSD (minimum), NVMe or SATA via USB 3.0
    • Why: The Bitcoin blockchain is ~600GB as of April 2025 and grows ~50-60GB yearly. 2TB ensures years of headroom. SSDs are faster and more reliable than HDDs for blockchain access and app data. NVMe (on Pi 5) or SATA-to-USB (Pi 4/5) leverages USB 3.0’s speed (up to 5Gbps).
    • Avoid: HDDs (slow, prone to failure under constant use) or <1TB drives (fill up too quickly).

3. Power Supply

  • Spec: Official Raspberry Pi Power Supply (5.1V, 3A for Pi 4; 5.1V, 5A for Pi 5)
    • Why: Underpowered supplies cause instability, SD card corruption, or SSD dropouts. The Pi 5’s higher power draw (especially with NVMe) demands 5A. Official supplies maintain stable voltage under load.
    • Avoid: Third-party chargers or USB hubs—most can’t deliver consistent current.

4. Cooling

  • Solution: Active cooling (fan) + heatsinks, or a quality case like Argon ONE V2/V3 or FLIRC
    • Why: The Pi throttles performance when overheated (e.g., during IBD or heavy app use). A fan keeps the CPU below 70°C, and heatsinks dissipate heat from the SoC and RAM. Cases like Argon ONE add power buttons and better airflow.
    • Avoid: Running without cooling—leads to thermal throttling and potential hardware damage.

5. Networking

  • Connection: Ethernet (1Gbps recommended)
    • Why: A stable, fast connection is critical for blockchain syncing and app reliability. Ethernet outperforms Wi-Fi in uptime and bandwidth, especially for a node that should run 24/7.
    • Avoid: Wi-Fi unless absolutely necessary—less reliable and slower.

6. Case (Optional but Recommended)

  • Spec: A case with SSD/NVMe support (e.g., Argon M.2, Geekworm X890)
    • Why: Protects the Pi, integrates storage, and often includes cooling. M.2 cases support NVMe on Pi 5 or SATA SSDs via USB.
    • Avoid: Exposed boards—prone to dust, shorts, or physical damage.

Example Setup

  • Raspberry Pi: Pi 5, 8GB RAM
  • MicroSD: 32GB SanDisk Extreme Pro
  • Storage: 2TB Samsung 870 EVO SATA SSD (via USB 3.0) or Samsung 970 EVO Plus NVMe (Pi 5 with NVMe HAT)
  • Power: Official Raspberry Pi 27W USB-C (5A)
  • Cooling: Argon ONE V3 (fan + heatsinks)
  • Network: Ethernet cable to a gigabit router

Why This Eliminates Problems

  1. Performance: 8GB RAM and a fast SSD handle IBD (1-2 days vs. weeks on weaker setups) and multitasking (e.g., Bitcoin + Nextcloud).
  2. Storage: 2TB covers the blockchain’s growth for 5+ years, avoiding mid-run upgrades.
  3. Reliability: High-endurance SD cards and proper power prevent corruption or crashes.
  4. Heat: Cooling stops throttling, ensuring 24/7 uptime.
  5. Future-Proofing: Pi 5 and NVMe support emerging Umbrel features and heavier apps.

Notes

  • Cost: ~$200-$300 total, depending on SSD prices and case choice.
  • Pi 5 vs. Pi 4: Pi 5 is faster and supports NVMe natively (with a HAT), but Pi 4 is cheaper and fully stable with Umbrel now. Choose based on budget and patience for Pi 5 optimization.
  • Overkill?: If you only run a Bitcoin node, a Pi 4 with 4GB RAM and a 1TB SSD works, but the above specs ensure no upgrades or tweaks later.

Let’s say you need to start over?

There isn’t an official script specifically designed to “remove” Umbrel from a Raspberry Pi in the same way there’s an installation script (like curl -L https://umbrel.sh | bash). Umbrel doesn’t provide a dedicated uninstaller because it’s typically installed as an operating system (umbrelOS) or as a set of Docker containers and configurations on top of an existing OS (like Raspberry Pi OS). However, you can effectively remove Umbrel by reversing the installation process, depending on how it was set up. Here’s how you can do it:

If You Installed umbrelOS (Full OS Image)

If you flashed umbrelOS onto a microSD card or another drive (e.g., NVMe or USB) using a tool like Balena Etcher, “removing” Umbrel is as simple as reformatting the drive or replacing it with a different OS:

  1. Power Down the Raspberry Pi: Safely shut down your Raspberry Pi (via the Umbrel dashboard under Settings > Shutdown, or by unplugging it if the dashboard isn’t accessible).
  2. Remove the Storage Medium: Take out the microSD card, NVMe drive, or USB drive where umbrelOS is installed.
  3. Reformat the Drive: Insert the storage device into a computer and use a tool like Disk Utility (macOS), Disk Management (Windows), or gparted (Linux) to wipe and reformat it. This erases umbrelOS entirely.
  4. Optional - Install a New OS: If you want to reuse the Raspberry Pi, flash a new OS (e.g., Raspberry Pi OS) onto the drive using Raspberry Pi Imager or a similar tool.
  5. Reassemble and Boot: Insert the reformatted or newly flashed drive back into the Raspberry Pi and power it on. Umbrel will be gone.

If You Installed Umbrel on Top of Raspberry Pi OS (Script Method)

If you used the script method (curl -L https://umbrel.sh | bash) to install Umbrel on an existing Raspberry Pi OS, Umbrel runs as a set of Docker containers and files in the ~/umbrel directory. To remove it:

  1. Stop Umbrel Services:
  • Open a terminal on the Raspberry Pi (via SSH or direct access).
  • Navigate to the Umbrel directory: cd ~/umbrel.
  • Stop all running containers: sudo ./scripts/stop.
  1. Remove Umbrel Files:
  • Delete the Umbrel directory: sudo rm -rf ~/umbrel. This removes the core Umbrel software, configurations, and Docker Compose files.
  1. Remove Docker Containers and Images:
  • List all Docker containers: docker ps -a.
  • Remove Umbrel-related containers: docker rm <container_id> (replace <container_id> with the IDs of Umbrel containers, e.g., those labeled with umbrel_).
  • Remove Umbrel Docker images: docker images to list them, then docker rmi <image_id> for any Umbrel-specific images.
  1. Uninstall Docker (Optional):
  • If you no longer need Docker, remove it: sudo apt-get remove --purge docker docker.io containerd runc.
  • Clean up unused packages: sudo apt-get autoremove.
  1. Delete Data (If Separate):
  • If you configured Umbrel to store data on an external drive (e.g., SSD), connect it to a computer and reformat it to erase blockchain data, app data, etc.
  1. Reboot: Restart the Raspberry Pi with sudo reboot to ensure no residual processes remain.

Why No Official Removal Script?

Umbrel’s design assumes you’re either running it as a dedicated OS (umbrelOS) or managing it manually on a base OS. In the former case, wiping the drive is the natural removal method. In the latter, it’s a lightweight Docker-based setup that doesn’t deeply integrate into the system, so manual cleanup suffices. The community hasn’t widely demanded a removal script, and Umbrel’s developers focus on improving installation and usage rather than uninstallation.

Final Notes

  • Backup First: If you want to preserve any data (e.g., Bitcoin wallet seed phrases or app configurations), back them up before removing Umbrel.
  • No Script Exists (As of Now): As of April 6, 2025, no official uninstall script exists on Umbrel’s GitHub or website. If you’re comfortable with scripting, you could write a bash script to automate the Docker cleanup steps above, but it’s not provided out of the box.
