Create a debdiff

You may also read about doing debdiffs here.

Using ubiquity-slideshow-ubuntu as an example here. We're pulling from released source, which you might not want to do. You might want to first branch off the original bzr branch.

First, get the source and the build dependencies.

  • $ pull-lp-source ubiquity-slideshow-ubuntu $ sudo apt-get build-dep ubiquity-slideshow-ubuntu

$ pull-lp-source ubiquity-slideshow-ubuntu $ sudo apt-get build-dep ubiquity-slideshow-ubuntu

This will pull down a few things. We need the source dir where to make changes, and the .dsc file for making the debdiff.

So, let's head to the source dir, and make our changes.

  • $ cd ubiquity-slideshow-ubuntu-67

$ cd ubiquity-slideshow-ubuntu-67

Now, do your changes to the source.

Edit the changelog to include your changes

  • $ dch -i

$ dch -i

Example of what it looks like initially:

ubiquity-slideshow-ubuntu (67ubuntu1) UNRELEASED; urgency=low

-- Kaj Ailomaa zequence@mousike.me Sun, 10 Mar 2013 23:07:01 +0100

Example of how it could look like after I'm done. Notive I've added a description of the change, replaced "67ubuntu1" with 68, to make it a new version, and set the release name to "raring".

ubiquity-slideshow-ubuntu (68) raring; urgency=low

    • Updated the ubuntustudioslideshow for new release
  • Updated the ubuntustudioslideshow for new release

-- Kaj Ailomaa zequence@mousike.me Sun, 10 Mar 2013 23:07:01 +0100

When you're done, your dir will be renamed to ubiquity-slideshow-ubuntu-68. Now, we rebuild the source. This will also sign the dsc and change files.

  • $ debuild -sa -S

$ debuild -sa -S

To get the debdiff, we do:

  • $ cd ../ debdiff ubiquity-slideshow.dsc ubiquity-slideshow.dsc > ubiquity-slideshow.debdiff

$ cd ../ debdiff ubiquity-slideshow.dsc ubiquity-slideshow.dsc > ubiquity-slideshow.debdiff

Now, you need to pass the debdiff to a sponsor who can use it to patch the debian source, and upload the new version to the repo. It's simply a textfile.
