Firstly, download the zip file containing the Cashless Guru Raspberry Pi OS image – you can find the latest version URL here.

Once you’ve downloaded the image, you’ll need to extract it:
$ unzip guru-std-1.0.2.zip
Next insert your SD card and identify the correct path using
$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 111.8G 0 disk └─sda1 8:1 0 111.8G 0 part /
In our case, the SD card is sdf and so we next need to unmount the volumes and then we are in a position to write the image to the card.
$ sudo umount /dev/sdf1 $ sudo umount /dev/sdf2 $ sudo dd if=guru-std-1.0.2.img of=/dev/sdf bs=1M sync=conv $ sudo umount /dev/sdf1 $ sudo umount /dev/sdf2
The above command will not produce any output and can take a long time to complete. You will receive a terminal prompt when the command has succeeded, an error will display if it has failed.
Your SD card is now ready to insert in to your Raspberry Pi.
