Thanks Adam. I removed all the casper installs as per your instructions and reinstalled casperfpga. I still get the similar error as before. And the version is also showing up as unknown.
So I removed the packages in /usr/local/.. as you said, downloaded all the files in the location you had suggested, cd'ed in to the new folder and installed casperfpga as mentioned in the tutorial. I am able to connect to the red pitaya board, the led is blinking and everything, but get the similar error as before when reading the snapshot.
