TLDR: The `exports.sh` file was empty in my bitcoin app directory, so I replaced it with a working one. I copied the `exports.sh` from the `/home/umbrel/umbrel/app-stores/getumbrel-umbrel-apps-github-53f74447/bitcoin/exports.sh` path and restarted my node. Then the bitcoin app started properly. Use this command to do exactly what I did (you may have to modify the copy path a bit): ```bash # Change directory to bitcoin app cd ~/umbrel/app-data/bitcoin/ # Backup existing exports.sh file mv exports.sh exports.sh.backup # Copy working exports.sh file from "app-stores" directory cp ~/umbrel/app-stores/getumbrel-umbrel-apps-github-53f74447/bitcoin/exports.sh $PWD ``` * * * For others having the issue where it seems like environment variables aren’t set and have their apps stuck on starting or restarting forever, I seem to have found a fix. My bitcoin app was stuck on starting which prevented many other apps that depended on it from running, obviously. For context, I am running on Raspberry Pi 4 and recently updated to version umbrelOS 1.4.2. I originally started before the 1.0 update so definitely have legacy stuff laying around. This problem started immediately after updating to 1.4.2. I was having the following output when I tried to troubleshoot: ```bash Command failed with exit code 1: /opt/umbreld/source/modules/apps/legacy-compat/app-script logs bitcoin time="2025-06-08T17:52:09Z" level=warning msg="/opt/umbreld/source/modules/apps/legacy-compat/docker-compose.app_proxy.yml: the attribute `version` is obsolete, it will be ignored, please remove it to avoid potential confusion" time="2025-06-08T17:52:10Z" level=warning msg="/opt/umbreld/source/modules/apps/legacy-compat/docker-compose.tor.yml: the attribute `version` is obsolete, it will be ignored, please remove it to avoid potential confusion" time="2025-06-08T17:52:10Z" level=warning msg="/opt/umbreld/source/modules/apps/legacy-compat/docker-compose.common.yml: the attribute `version` is obsolete, it will be ignored, please remove it to avoid potential confusion" time="2025-06-08T17:52:10Z" level=warning msg="networks.default: external.name is deprecated.
