Hello Community.
I have found some posts about similar or same topic, but those solutions haven’t worked so far.
To begin with, I was gonna update the LND app on Umbrel OS V.0.5.4, on Rasp.Pi 4, when somewhere in middle of the process an error message appeared, which I unfortunately didn’t take a screenshot of 
And the update process was stopped and canceled.
I decided to reboot the node, which had been running non-stop for about 2-3 months since last reboot.
But when it was rebooting the error message “Failed to start containers” appears.
After I had run the debug script I notice these errors, saying;
Umbrel logs
ERROR: The Compose file ‘./docker-compose.yml’ is invalid because:
networks.default.ipam.config.subnet is invalid: should use the CIDR format
services.tor_proxy.ports contains an invalid type, it should be a number, or an object
services.auth.ports contains an invalid type, it should be a number, or an object
services.nginx.ports contains an invalid type, it should be a number, or an object
Tor Proxy logs

I found some suggestions about similar topic here in umbrel community forum and in the Official Umbrel Troubleshooting Guide.
Also older soluition f.ex. from 2021 by @21isenough.
However, those suggestions didn’t work for me.
The debug script output also showed in the Filesystem info that the /dev/root was in 100% used, so I truncated some logs in /var/logs/ by follow a post I found by @smolgrrr.
So after I got some space back in /dev/root/
I rebooted again, but still had the same issue is on going and same error message when debug is repeated.
The following methods I have found here in the forum and tried to solve this issue with, with no success so far:
- Shutdown and restart the node with the command
sudo ~/umbrel/scripts/stop && sudo ~/umbrel/scripts/start - Stopped the docker via systemctl command,
sudo systemctl stop docker && sudo rm -rf /var/lib/docker/* && sudo reboot - reFlashed the UmbrelOS to a new sd card, but it shows the same “containers” error message.
- Cloned the SSD external disk to new and larger SSD external disk, in case this where related to some SSD disk issue.
Now I’m kind of running out of ideas on what try to do next, and wanted to check if the community would have some more ideas to share about this topic.
Kind regards.
