    Thank you.  Can you confim if unRar has been removed?  It is not mentioned in the Changelog, but RAR is no
    longer mentioned in the man pages, the lib/Codecs directory is now empty, and 7z extractions from .rar files
    produces an "Unsupported Method" error message.  At least for me.  Did I miss a configuration step, instead?

    Thanks

    Can you tell us how did you get p7zip binaries ?
    1) with a package provided by your linux distribution ?
    or
    2) using p7zip_9.20_x86_linux_bin.tar.bz2 from sourceforge (https://sourceforge.net/projects/p7zip/files/p7zip/9.20/) ?
