[Bug 70610] Re: Unable to uncompress .Z files without a "compress" binary

[Javier P.L.]

Thanks for letting us know the issue is resolved. This issue was fixed
as pointed out in tar 1.25:

http://savannah.gnu.org/forum/forum.php?forum_id=6595

All ubuntu versions from Ubuntu Oneiric, use tar 1.26 so I'm marking
this as fixed.

Title:
  Unable to uncompress .Z files without a "compress" binary

Status in “tar” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: tar

  Tar appears unable to uncompress a .Z file (produced with the
  "compress" utility) without the "compress" binary being present on the
  system.  This should not be necessary because "gzip" is (and always
  has been) quite capable of uncompressing compress-ed binaries.

  To repeat:

  1. obtain a .tar.Z file, e.g.
  ftp://aixpdslib.seas.ucla.edu/pub/ldd/RISC/5.1/exec/ldd.1.0.tar.Z

  2. Execute:
      tar xf ldd.1.0.tar.Z

  Expected result: the tar file is uncompressed.

  Actual result: error:

  tar: compress: Cannot exec: No such file or directory
  tar: Error is not recoverable: exiting now
  tar: Child returned status 2
  tar: Error exit delayed from previous errors

  As a workaround, one can add the "z" flag to force the use of gunzip
  for decompression.  However, the "z" flag should not be necessary and
  is confusing, since tar is obviously quite capable of recognizing the
  format.
