PPA - Section 'main' is not valid - what to do?

[Dusan Zatkovsky <msk.conf@xxxxxxxxx>]

Hello there.

I am trying to use ubuntu PPA. I have followed steps from 
https://help.launchpad.net/PPAQuickStart ( activated ppa, imported gpg key, 
signed ), but i still can't upload packages.

I have created simple source package and tried to upload it to ppa.

Here is reply mail from ppa:
