Packaging AIR application in .deb installer

Hi!

I am developping an application for a company to control the production of a manufacturer that will run in a Linux machine. I was using Adobe Flex SDK 4.1 in the development of the application, but now I am using the Adobe Flex SDK 4.5.1 to pack the application in a native installer for Linux.

The command that I am using to compile the application is:

adt -package -storetype pkcs12 -keystore certificate.p12 -storepass password -target native application-3.3.0.deb application-app.xml application.swf

but I get the following error:

Packaging failed. Make sure your computer time is in sync and your certificate is valid

After that, I checked if the certificate was valid:

adt -checkstore -storetype pkcs12 -keystore certificate.p12 -storepass password

and it says it is a valid password.

Probably I'm not using the right Adobe AIR SDK. Where can I get the Adobe AIR SDK 2.6 for Linux?

Extra info:

Adobe Flex SDK version: 4.5.1.21328

ADT version: 2.6.0.19120

What's wrong?
