Extremely new to the command line (read: no clue what I'm doing), so I have been trying to teach myself some basic commands by doing some run of the mill stuff. Currently trying to install Marathon on my computer by following the instructions on: https://github.com/Aleph-One-Marathon/alephone/wiki/Linux%20Install%20Instructions
I am trying to run,
tar xjvf AlephOne-20150619.tar.bz2
But I get the error,
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2.
tar: Error is not recoverable: exiting now.
Can anyone tell me what's going on or offer some suggestions as to what I should do? Any help would be much appreciated.
