Failed to Start Docker Application Container Engine

[OpenWaterSwim]

I began running Umbrel successfully nearly a year ago with minimal issues on several nodes. I recently lost power and one of my nodes returned as normal, but the other did not. I have a bitcoin wallet and lightning channels on this node. I have my seed and backups. Connecting via browser, I receive the following Error: Failed to start containers.

I am able to connect via ssh and verify that the SD card with the OS and SSD drive are functional, but continually receive this error when connecting via any browser. I bought a new micro SD card and flashed it to Umbrel v0.5.0. One interesting note is that my password reset to the default password when I began receiving this error.

---

Here is my setup:

• Raspberry Pi 4B - 8GB
• Samsung Portable SSD T7 - 2TB
• SanDisk 32GB Ultra microSDHC UHS-I Memory Card
• GeeekPi Armor Lite Aluminum Heatsink with PWM Speed Control Fan for Raspberry Pi 4 Model B

Here is the debug log from this Umbrel node.

I admit I am out of my depth here, but it appears that the Docker Application Container Engine is the issue. I am just not sure how to troubleshoot from here. I appreciate any helpful posts, links, or advice. Thank you for your time and consideration.

Hi
I got the same issue and i’ve just solved it!
I’ve first flashed the micro sd. But nothing changed.
Then I followed this steps :

Step 1 - Enter using SSH into your Umbrel node:

Step 2 - stop Umbrel node with:

cd umbrel
sudo systemctl stop umbrel-startup

Step 3 - clean / reconfigure the broken container:

sudo rm .env --> got an error because .env did not existed. No probs
sudo ./scripts/configure

Step 4 - apply latest Umbrel update (replace the version number with the latest):

sudo ./scripts/update/update --repo getumbrel/umbrel#v0.5.0

Restart your node:

UmbrelOS (RPi) use sudo systemctl start umbrel-startup

Worked fine for me! I hope it’s gonna help you
Cheers
Pierre

Pierre:

Thank you for your reply. I appreciate any and all suggestions as I feel like I have tried plenty. At least through all this troubleshooting, I learn with each new attempt to fix my issue. I have also been able to help others while learning, so this is all a plus as I believe I am then able to give back to the community.

When I get to step 3 and run the following command
sudo .scripts/configure

I receive the error message regarding the Docker daemon.

See ‘docker run --help’.

I tried the following to see if I could fix the Docker, but there still seems to be a problem with my docker-compose.yml file.

cd umbrel
sudo systemctl stop docker.service
sudo systemctl stop docker.socket
sudo rm -rf /var/lib/docker/* && sudo umount /var/lib/docker || true && sudo rm -rf /mnt/data/docker/*
sudo reboot

However, this likewise did not correct my issue. Thank you for your suggestion. We will figure it out.

[supriseflash]

Merci Pierre. This helped fixed a separate issue I had with the dockers not being able to fully shut down and reboot.

[sleepingsexton]

Also having the same issue. Did you figure it out?

[suhask]

I am also having the same issue. Did anyone figure this out yet?

[Groove]

hello, i am stuck here with this same issue…

[smolgrrr]

Hi @Groove, have you tried the following, and if so could you please share your troubleshooting logs?

Step 1 - Enter using SSH into your Umbrel node:

Step 2 - stop Umbrel node with:

cd umbrel

sudo ./scripts/stop

Step 3 - clean / reconfigure the broken container:

sudo rm -f .env && sudo ./scripts/configure

Step 4 - Restart your node:

sudo ./scripts/start

@mayank

If you are unable to access your Umbrel through a web browser, you can generate troubleshooting logs from the command line by following these steps:

1. Connect to your Umbrel device by following the instructions in How to SSH into Umbrel on a Raspberry Pi or by accessing a terminal on your Linux machine.
2. Run the following command. If you are on a Linux machine, you may need to replace ~ with the path to your installation directory, as described in Troubleshooting on Linux:sudo ~/umbrel/scripts/debug

Please share them from here https://pastebin.com/

It appears your Umbrel is not up-to-date- this may resolve the issue.

Try running the following

sudo ~/umbrel/scripts/update/update --repo getumbrel/umbrel#v0.5.4

[Frog]

Hello, I have followed this with my node after an unsuccessful trial to replace my 5.0.4 with 1.1.0 on a new SD card.
When I reverted back to the old card I had the container issue.
The first step was the official support method restarting the container which didn’t help.

Then I followed the steps in his thread without completely understanding what I was doing. After the cleanup and upgrade, I ended with the start page of not not-configured node. Asking me to set up the new account. This is a complete disaster for me because I had a Bitcoin wallet, a Lightning node with 7 quite big channels and BTCPay server to receive Lightning invoices. Now I am afraid to move an inch in my troubleshooting/recovery not to lose everything.
I do have seed, I do have ssh access to the node, I do have fresh channels backup, I have a backup of the most files I took before the disaster (/etc, /home ) and I believe most of the data remained intact on the node M2 drive. Only the configuration of the node has been wiped out by the steps from Pierre. Please help me and suggest the node recovery approach.

I have reviewed the configure script which did the configuration reset. So I have a clue which files were updated.

Remove intermediary files if they exist from any

previous unclean configuration run

[[ -f “$NGINX_CONF_FILE” ]] && rm -f “$NGINX_CONF_FILE”
[[ -f “$TOR_PROXY_CONF_FILE” ]] && rm -f “$TOR_PROXY_CONF_FILE”
[[ -f “$TOR_SERVER_CONF_FILE” ]] && rm -f “$TOR_SERVER_CONF_FILE”
[[ -f “$ENV_FILE” ]] && rm -f “$ENV_FILE”

Copy template configs to intermediary configs

[[ -f “./templates/nginx-sample.conf” ]] && cp “./templates/nginx-sample.conf” “$NGINX_CONF_FILE”
[[ -f “./templates/torrc-proxy-sample” ]] && cp “./templates/torrc-proxy-sample” “$TOR_PROXY_CONF_FILE”
[[ -f “./templates/torrc-server-sample” ]] && cp “./templates/torrc-server-sample” “$TOR_SERVER_CONF_FILE”
[[ -f “./templates/.env-sample” ]] && cp “./templates/.env-sample” “$ENV_FILE”

So I am thinking of restoring .env file from the backup and restart. I will back up the current one as well. Any objections?
Anything else to restore at the same time?
I am super vigilant after my f*ck up.

Finally, the node recovered, with no losses.
I just needed to set the password for the Umbrel start page, which was scary and fresh install apps from the store. Bitcoin synchronized the last 5 missing blocks (must have been running well in the background) and Lightning remains configured. Good design of Umbrel!
I will need to reconfigure nginx as BTC pay server is not responding over SSL.

I think I would need a test environment for these upgrades. Not as easy as described in the upgrade tutorial.
I also can’t imagine losing data on the M2 drive. That would be a disaster with my skills and the recovery time needed to sync with the blockchain.

Great to hear it was resolved!
I’d suggest checking out Cloudflared for BTCPay.
