trusty ppa building from bazaar

bzr-builder will convert a 3.0 (quilt) package to 3.0 (native) if it's unable to recreate the upstream tarball using pristine-tar. This conversion previously worked fine in most cases, but dpkg in trusty recently started rejecting native packages with non-native versions, causing converted source packages with versions containing hyphens to fail to build.

You'll need to either switch to a native version string, or provide the necessary pristine-tar data in the branch, probably using 'bzr import-upstream' as described at <http://doc.bazaar.canonical.com/plugins/en/builddeb-plugin.html>.

Hello,
I have the same isso with a launchpad recipe process:

https://code.launchpad.net/~pythonxy/+recipe/spyderlib-daily-via-github
https://code.launchpad.net/~pythonxy/+archive/pythonxy-devel/+recipebuild/624654/+files/buildlog.txt.gz

"
dpkg-source: error: can't build with source format '3.0 (native)': native package version may not have a revision
"

What can I do to keep the process going?

Kind regards.

Hello,

why bzr-builder will be convert from the newer quilt to the older native version:

I don't understand.

And a parameter description also does not help.

My first comment describes the situation, and how you can recover from it. Is there some part of it that you don't understand?

@wgrant

May I ask:

Why do the PPA builder work for all Ubuntus except for Trusty?

Any how can I change my rules in order to let the Trusty wor again?

I also found this:
"

If you convert it to 3.0 (native), then the quilt patches won't be applied.

You could apply them buy using dh $@ --with quilt, if the package uses dh, or manually calling the patch and unpatch commands during the build.

As I said in my first comment: "This conversion previously worked fine in most cases, but dpkg in trusty recently started rejecting native packages with non-native versions, causing converted source packages with versions containing hyphens to fail to build."

You cannot fix it with a change to debian/rules. The problem is that the most recent entry in debian/changelog has a hyphen in the version, which signifies that there is an upstream tarball (orig.tar.*). You need to remove the hyphen to make it a native package, or tell Launchpad how to construct the upstream tarball. bzr-builder uses pristine-tar to reconstruct the orig.tar.* from the branch; see http://doc.bazaar.canonical.com/plugins/en/builddeb-plugin.html#import-upstream for how to add the necessary metadata to your branch.
