[cobalt-developers] PKGs not working on XTR?

["Leslie Herps" <herps@xxxxxxxxxxxxxx>]

When I try and install a PKG through the CP GUI I ALWAYS get this

There was an error verifying the package file. It may be corrupted, or it
may not have the correct authentication information. The software package
was not installed.

However, untarring it WILL work so the package is fine... (Official Cobalt
PKG)....

Any idea's?
(PS: It's an XTR machine)
