How do I apply the fixes suggested from the App Review Board to my app?

First of all, read carefully what the reviewer is asking you to do on the e-mail. It will generally be either a request for information or a prompt to address some issues with your app.

In all cases:

• Reply to the information request using the Feedback tab on your submission in My Apps
• Optionally, if you don't receive a reply in a few days, send an e-mail reminder to the ARB mailing list.

If the ARB has done some changes to your app, apply those changes:

• Merge changes - The e-mail you got most probably contains a link to a branch with some suggested changes.
  • Run bzr merge lp:<branch-with-the-fixes> on your source tree to merge in the changes
  • Then commit them with the bzr commit command (or optionally quickly save if you use Quickly)
• Build and upload a new package - Build a new package after you've applied the changes:
  • Run the debuild -S command in your source tree to build a local source package
  • Run dput ppa:yourusername/ppa ../projectname_*_source.changes to upload the local source package to your remote PPA in Launchpad
• Give feedback Don't forget to reply in the Feedback tab as explained above
