[Bug 146225] Re: bunzip2 cannot extract files

[Phillip Susi]

Wait, I got it.. I see now, you have to mount the fs with the files
owned by root, then try to unzip it NOT as root.


** Summary changed:

- bunzip2 cannot extract files
+ bunzip2 refuses to extract a file if it can't set the mode

** Package changed: ntfs-3g (Ubuntu) => bzip2 (Ubuntu)

** Changed in: bzip2 (Ubuntu)
   Importance: Undecided => Low

** Changed in: bzip2 (Ubuntu)
       Status: Incomplete => Triaged

** Description changed:

- Binary package hint: ntfs-3g
+ If bunzip2 fails to chmod the extracted file, it bails out and deletes
+ it.  It should not do this.
  
- this is gutsy, ntfs-3g version 1:1.710-1ubuntu4
+ To reproduce, mount an ntfs filesystem with the uid=0 option so files
+ are owned by root, then try to bunzip2 a file as non root.  Since the
+ file is owned by root, the chmod fails.  This should not be a fatal
+ error.
+ 
+ Original Description:
  
  If I try to decompress any bz2 files I get this error
  bunzip2: I/O or other error, bailing out.  Possible reason follows.
  bunzip2: Operation not permitted
-         Input file = odf-converter_1.0.0-1~getdeb1_i386.deb.bz2, output file = odf-converter_1.0.0-1~getdeb1_i386.deb
+         Input file = odf-converter_1.0.0-1~getdeb1_i386.deb.bz2, output file = odf-converter_1.0.0-1~getdeb1_i386.deb
  bunzip2: Deleting output file odf-converter_1.0.0-1~getdeb1_i386.deb, if it exists.
  
  with gunzip I get 2 these errors
  gzip: odf-converter_1.0.0-1~getdeb1_i386.deb: Operation not permitted
  gzip: odf-converter_1.0.0-1~getdeb1_i386.deb: Operation not permitted
  
  but at least the file is created
