I am a truenas novice running scale 25.10.3 trying to install an BorgWarehouse from the Discover Apps page. There doesn’t seem to be comprehensive instructions for a truenas/docker novice to set up the app available directly from the app page, but I tried to struggle through the settings. Searching around the internet and trying to get some rudimentary docker knowledge, I came up with some settings that the app install found acceptable. I hit install and an install progress window appeared and began the install. It ultimately failed saying to refer to /var/log/app_lifecycle.log for details. Trying to sudo cat this file on my truenas server gave me unexpected difficulty, since all the newlines printed as “/n” making the output harder to read than necessary. The log starts with “(ERROR) app_lifecycle.compose_action():58 - Failed ‘up’ action for ‘borgwarehouse’ app: …”, followed by a bunch of pulling, extracting, verifying, download complete, etc. lines. Then several lines after starting the borgwarehouse container, the end of the log file says, “Error\ndependency failed to start: container ix-borgwarehouse-borgwarehouse-1 is unhealthy\n”. There isn’t any indication what this dependency is or how I might be causing it with my attempt at setting the app config. Sorry, that I can’t show the settings I tried, since truenas seems to have left no trace of my install attempt. I think this is a recently added community app, so if anyone has succeeded in installing from the Discover page, please feel free to help educate me. 
What storage type did you try to set up? iXVolume or Hostpath?
If you selected Hostpath it may be a permission issue. According to the truenas info page on borgwarehouse the app wants to run as uid 1001 and the cron container as 568 (that’s the default apps user)
I don’t know if truenas has a buildin user that correlates to uid 1001. You may have success by ticking the “Enable ACL” Checkbox and adding an entry for ID 1001 like this
