I found this software to format my SD card (attached). The problem is that it always return an exit code of 255 and then the error message:
Ready to install utility software. Please ensure your Arduino Yun is connected to internet.
Ready to proceed (yes/no)? answer yes
Updating software list…
Software list updated. Installing software (this will take a while)…
err. installing e2fsprogs dosfstools fdisk rsync kmod-fs-ext4
How do I get past this point to the actual formatting of the SD card?
