Enable XDG user directories
The current image does not include support for XDG user directories (Documents, Pictures, Music, etc.) out of the box. This means that Flatpak applications that use the xdg-* permissions will fail at run-time.
This can be enabled by installing the xdg-user-dirs package.
If necessary, the user's directories can be created by running the xdg-user-dirs-update tool.
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
