Problem installing FileBrowser Quantum

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:

Definitely 1.1.3 is working (for me). Try this version.

Search in App Store: quantum

Hover mouse cursor over blue button Install, Custom install appeared. Click Custom install.

Yes, 1.1.3 installed OK.

Previously I had tried clean installs of v1.2.4, but without success.
