Cannot update Tango Core - "Package file was not signed correctly"

Got my Tango tablet last night and tried to get it going by installing required packages. Updating "Project Tango Core" app failed. Here's the error I get:

Error: Package file was not signed correctly

Anybody else seen this and know how to fix it?
Here's some info that may be required:

system info and versions

Solution

  • Looking at the build number that you have pictured above, this is an old OS build. In order to fix this issue you need to perform an update on the system software (Settings->About Tablet->System Updates).

    Once you have updated to the latest software version, currently Cantor, this issue should resolve itself.

    Edit : If your tablet does not see the update you may need to perform a factory data reset (Settings->Backup and Reset->Factory Data Reset).
