Installed Dolphin from the App Store, like that split plane feature. Alas I cannot seem to access mounted SSH devices from my local network. Probably something very obvious?
This is due to access permissions. Flatpak installations do not have complete access to your system, so you need to explicitly grant permissions. Fortuntaely, it's not too difficult.
To give any software you've installed from the App Store permission to access a file location, do this:
- Open Terminal
- Grant permission:
Note: If you have a path with spaces or special characters, be sure to wrap the
sudo flatpak override <package_name_here> --filesystem=<path_here>
Later, if you need to remove access to a location, use the
--nofilesystem option to remove permissions:
- Open terminal.
- Revoke permission:
sudo flatpak override <package_name_here> --nofilesystem=<path_here>
If you would like to know more about the different options that are available for App Store-installed app permissions, you can read about the Flatpak sandbox here.
