title: unpacking of archive failed on file error when installing a rpm pkg
body: <p>I got an error shown below when I'm installing a rpm pkg:<br/>
  <em>error: unpacking of archive failed on file /usr/local/xxxx/help/html/xxx.chm/xxx.html;56498998: cpio: Digest mismatch</em></p>
  
  <p>I've tried to find some related topics about this error by google.<br/>
  Digest mismatch seems to be happened mostly in the %install step when someone building a rpm pkg.</p>
  
  <p>Most of the case about the error: unpacking of archive failed on file was end by cpio:open failed. I think this is different from my error.</p>
  
  <p>So do anyone have some ideas about this error ?</p>
