A -J option unknown means your distro is missing the xz-utils package, which is required for tar to have support for untarring xz compressed files. You will either need to get a modern implementation of tar and xz-utils compiled from source, or switch to another distribution of linux, or download the calibre linux tarballs on another computer and uncompress them manually then simply extract them in /opt/calibre and run calibre as
/opt/calibre/calibre
