If dd was used correctly
I used sudo dd if=/Path/to/LibreELEC.img of=/dev/sdX status=progress conv=fsync when I encountered the "Could not mount error".
Do you think there's anything wrong with it if I use it for LE and the SD card already had partitions on it? If so it would be nice to have a hint on the wiki I think because there's no LibreELEC USB-SD Creator for GNU/Linux.
