libisofs6 1.5.0-1 (i386 binary) in ubuntu focal

 libisofs creates ISO 9660 (aka ECMA-119) filesystem images which can either
 be written to POSIX file objects or handed over to libburn for being written
 directly to optical media.
 It can read metadata of ISO 9660 filesystems, manipulate them, and use them
 to produce new complete filesystem images or add-on images to be appended
 to the read filesystem image.
 Supported extensions to ISO 9660 are Rock Ridge, Joliet, AAIP, zisofs.
