backportpackage - helper to test package backports


backportpackage [additional options]
--upload <upload target>
<source package name or .dsc URL/file>

backportpackage -h


backportpackage fetches a package from one distribution release or from a specified .dsc
path or URL and creates a no-change backport of that package to one or more Ubuntu
releases release, optionally doing a test build of the package and/or uploading the
resulting backport for testing.

Unless a working directory is specified, the backported package is fetched and built in a
temporary directory in /tmp, which is removed once the script finishes running.

backportpackage is only recommended for testing backports in a PPA, not uploading
backports to the Ubuntu archive.


-d DEST, --destination=DEST
Backport the package to the specified Ubuntu release. If this option is
unspecified, then backportpackage defaults to the release on which it is currently

-s SOURCE, --source=SOURCE
Backport the package from the specified release, which can be any release of your
distribution or any of your distribution's parent distributions. If neither this
option nor --version are specified, then backportpackage defaults to the current
development release for your distribution.

-S SUFFIX, --suffix=SUFFIX
Add the specified suffix to the version number when backporting. backportpackage
will always append ~ubuntuDESTINATION.1 to the original version number, and if
SUFFIX is specified, it is appended to that, to get version numbers of the form
ORIGINAL_VERSION~ubuntuDESTINATION.1SUFFIX. If the backported package is being
uploaded to a PPA, then SUFFIX defaults to ~ppa1, otherwise the default is blank.

-b, --build
Build the package with the specified builder before uploading. Note for
cowbuilder(8) and pbuilder(8) users: This assumes the common configuration, where
the ARCH and DIST environment is read by pbuilderrc(5) to select the correct base

Use the specified builder to build the package. Supported are cowbuilder(8),
cowbuilder-dist(1), pbuilder(8), pbuilder-dist(1), and sbuild(1). The default is

-U, --update
Update the build environment before attempting to build.

-u UPLOAD, --upload=UPLOAD
Upload to UPLOAD with dput(1) (after confirmation).

-k KEYID, --key=KEYID
Specify the key ID to be used for signing.

Do not sign the upload.

-y, --yes
Do not prompt before uploading to a PPA. For everyone's safety, this option is
ignored if UPLOAD is ubuntu.

-v VERSION, --version=VERSION
If the --source option is specified, then backportpackage verifies that the current
version of source package in SOURCE is the same as VERSION. Otherwise,
backportpackage finds version VERSION of source package in your distribution's
publishing history, regardless of the release in which it was published (or if that
version is still current). This option is ignored if a .dsc URL or path is passed
in instead of a source package name.

-w WORKDIR, --workdir=WORKDIR
If WORKDIR is specified, then all files are downloaded, unpacked, built into, and
otherwise manipulated in WORKDIR. Otherwise, a temporary directory is created,
which is deleted before backportpackage exits.

-r, --release-pocket
Target the upload at the release pocket, rather than the -backports pocket. This
is required for Launchpad PPAs, which are pocket-less (and the default, when the
upload target is a PPA).

-m MIRROR, --mirror=MIRROR
Use the specified mirror. Should be in the form http://archive.ubuntu.com/ubuntu.
If the package isn't found on this mirror, backportpackage will use Launchpad.

-c BUG, --close=BUG
Include a Launchpad closer for the specified bug in the auto-generated changelog.
In the future, this may actually close the bug, but currently does not.

-l INSTANCE, --lpinstance=INSTANCE
Use the specified instance of Launchpad (e.g. "staging"), instead of the default of

Do not read any configuration files, or configuration from environment variables.


Used to determine the uploader (if not supplied as options). See
ubuntu-dev-tools(5) for details.

All of the CONFIGURATION VARIABLES below are also supported as environment variables.
Variables in the environment take precedence to those in configuration files.


The following variables can be set in the environment or in ubuntu-dev-tools(5)
configuration files. In each case, the script-specific variable takes precedence over the
package-wide variable.

The default value for --builder.

The default value for --update.

The default value for --upload.

The default value for --workdir.

The default value for --mirror if the specified SOURCE release is an Ubuntu

The default value for --mirror if the specified SOURCE release is a Debian release.

The default value for --lpinstance.


Test-build in your PPA a backport of znc from the current development release to your
workstation's release, deleting the build products afterwards:

backportpackage -u ppa:user/ppa znc

Backport squashfs-tools from Maverick to both Karmic and Lucid and test-build both
locally, leaving all build products in the current working directory:

backportpackage -b -s maverick -d karmic -d lucid -w . \

Fetch a package from a PPA, backport it to Hardy, then upload it back to the same PPA:

backportpackage -d hardy -u ppa:user/ppa \
