The reason you're getting that error is because the
debian/source/format file says that this is a
3.0 (native) package.
As a bit of background info, the
debian/source/format file describes the format of the package. There are three formats available:
1.0: Specifies that the
debian folder and any changes that need to be made to other files in the upstream package will be in a
.diff.gz file. This results in a
.orig.tar.gz that contains the upstream tarball and
.diff.gz that includes changes/additions for packaging.
3.0 (quilt): Specifies that the
debian folder in a
.debian.tar.gz file, and that changes to the upstream files will be specified as separate patch files in the
debian/patches folder, and will use the quilt patch system.
3.0 (native): Same as
3.0 (quilt), but for packages that won't have any patches because the software/program itself is made by the distributors (Debian, Ubuntu, etc.), and so any changes are made directly to the files.
For the last two formats, the versioning formats are different.
3.0 (quilt) expects the version number followed by
-#ubuntu#. Some examples of this are
2.7-1ubuntu3 (from Ubuntu's standpoint, this means that the package was imported from Debian, but has Ubuntu-specific changes on top of it) and
3.4-2 (from Ubuntu's standpoint, this means that the package was imported from Debian, but has no Ubuntu-specific changes). Note that the version doesn't necessarily indicate whether there are changes made to the upstream tarball itself (patch files in
debian/patches), or whether they're just changes in building the package.
3.0 (native), there is no dash after the version. Some examples of this are
In your case, the version follows the
3.0 (quilt) format, but
3.0 (native). There are two things you need to do here:
(Recommended) Make any changes to the package in a separate patch. Take a look at Ubuntu's patches folder for the syntax. Note that the
series file specifies what patches in the folder should be applied and in what order. (lines starting with
# are ignored)
As for the version of your package, using
32.0-0ubuntu5ppa1 will work (watch the underscores and dashes).
