I have an NMU modue running AXP 1.5.3. When I try to install a a package (mine or helloworldXNMbundle.1.0.pkg) or when I try to upgrade to AXP 1.6.1 I have the following error message:
 
  Validating installed manifests ..
  Trying Third Party verification
  Validating installed manifest /sw/installed/manifest/timezone_manifest.sig
  Validation Error:  Unexpected EOF reading past Header
  Manifest signature validation failed for timezone_manifest.sig
 
What can I do to fix this?
 
Below is the full log for the upgrade to AXP 1.6.1:

Thanks.

 
All the files from the axp-k9.nme.1.6.1.tar.gz archive are already in the same directory. I fails when I try to run:
 
  # software remove downloadfiles
  # software install clean url ftp://10.10.0.1/axp-1.6.1/axp-k9.nme.1.6.1.pkg
 
Below are the MD5 sums of the files:
