How to mount xbian partition on ubuntu?

[OMID-313]

Hi everybody,

I recently installed Xbian on my RPi B+.

I wanted to have access to the contents of my SD card in my PC, using Ubuntu.
However, it fails to mount the xbian partition, and gives the following error:



I searched on the net, and realized that its file system type is BTRFS, and it has LZ4 compression.

Now the questions is this:

How can we have access to the contents of this SD card, using a PC/Laptop!?

(Note: For some reasons, I can neither use the xbian file manager, nor the SSH.)
