[backportpackage] fails if no GPG present

I also found no way to specify the key to use: there is no -k option and DEBSIGN_KEYID env variable do nothing.

This bug was fixed in the package ubuntu-dev-tools - 0.142

  * dgetlp: Require a UTF-8 locale, or it'll crash when displaying errors
    (LP: #979117)
  * pbuilder-dist: Don't try to enable -updates for Debian testing
    (LP: #993006)
  * pbuilder-dist, pull-debian-source, pull-lp-source, requestsync,
    reverse-depends, submittodebian, syncpackage:
    Handle outdated distro-info data. Fall back to sane defaults where
    possible. (Closes: #673957)

      (LP: #1002999)
  * submittodebian: Revert Ubuntu Maintainer mangling, and re-build the source
    package before diffing. (LP: #902233)

  [ Evan Broder ]
  * backportpackage: Add -c, --close flag to include a changelog closer.
  * backportpackage: Switch to ~ubuntu12.04.1-style version numbers
    instead of ~precise1, to make our version numbers more future-proof.
  * backportpackage: Pass -v to debuild with last published version
    number. This matches the way backports have traditionally been
    generated by archive admins.

Sorry, this says "0.142, Fix Released" but 12.04 LTS still lists "ubuntu-dev-tools 0.141"

Where exactly is this fix released? How can I determine this information on my own next time I stare at this screen?

Regards,

New versions are always released to the current development version of Ubuntu, which is currently 12.10 Quantal.

You can see the versions available in the different Ubuntu releases by visiting the package's overview page:
    https://launchpad.net/ubuntu/+source/ubuntu-dev-tools

If you would like the new version for 12.04 Precise, you have some options:
  * backport it yourself using backportpackage :)
  * request a backport: https://wiki.ubuntu.com/UbuntuBackports
  * see if the SRU team thinks this is a good candidate for a stable release update: https://wiki.ubuntu.com/StableReleaseUpdates

 * or install it from the PPA: https://launchpad.net/~udt-developers/+archive/daily

Stefano, could you do an SRU for precise?
