I am running CasaOS 0.4.15 on a ZimaBoard.
When I try to install FileBrowser Quantum, the installer runs but returns an error message. Portainer shows that there is a running container, but the app shows “App may not be available”.
Hi @sdmorris.
Check Your container’s log. You can access it under App’s Settings:
Or better way is install & use App Dozzle.
Whatever the problem is, there is no log!
Dazzle shows “config file /mnt/Drive2/AppData/big-bear-filebrowser-quantum/data/config.yaml does not exist, please create it or set the FILEBROWSER_CONFIG environment variable to a valid config file path”
But the file does exist.
I have also set FILEBROWSER_CONFIG, but that did not help.
Maybe You have permission problem…
Uninstall all.
3 dots… Hit uninstall and mark checkbox: delete userdata
My log:
