Calibre cbr cbz convert error FIX [Ubuntu Linux]

This should work on other linux as well.

Too solve this error you'll need to grab libunrar.so

1) go here: http://sourceforge.net/projects/calibre/files/ and download calibre-0.6.17-x86_64.tar.bz2

2) Or skip step 1 and download the single shit i uploaded http://www.megaupload.com/?d=MFCG0RL8

3) extract it theres a file inside called libunrar.so

4) copy libunrar.so into "/usr/lib" folder ull need to be root

5) done

Note: Not sure why this didnt came with the default karmic koala package, even if u install the unrar and rar package it doesnt come with the libunrar.so
