Hi there,
Just installed Umbrel on an Ubuntu 20.04 server and I love it so far. Fantastic software and so easy to use. I have one issue so far: I cannot install any apps from the app store, the installation just hangs forever. This is the log from karen when trying to install an app:
karen is getting triggered!
./karen: line 68: /mnt/bitcoin/umbrel/events/triggers/: Is a directory
karen is getting triggered!
This script must only be run on Umbrel OS
Got signal: app-install-btcpay-server
karen is getting triggered!
Setting up data dir for app btcpay-server...
sending incremental file list
./
sent 166 bytes received 23 bytes 378.00 bytes/sec
total size is 2,526 speedup is 13.37
Pulling images for app btcpay-server...
Define and run multi-container applications with Docker.
Usage:
docker-compose [-f <arg>...] [options] [COMMAND] [ARGS...]
docker-compose -h|--help
Options:
...
So it looks like something about the docker image pull for the app is failing, and instead docker just prints out the docker-compose usage help.
I have already tried stopping Umbrel, rebooting, and starting up again. No change.
Would appreciate any help 
Thanks
