[backportpackage] errors out on packages with no ubuntu revision

[Jeremy Bícha]

This worked last week, but now fails. I'm filing against ubuntu-dev-tools since I know that just got an update this week.

It also fails if I use -d unstable.

It's fallout from the backport version schema change.

The versions are now ~ubuntu12.04.1 instead of ~precise1 (as code names
are due to wrap in the foreseeable future)

That matches some code in the Ubuntu Vendor plugin to dpkg-source that
looks for "ubuntu" in the version without @ubuntu.com in the Maintainer.

This can be lowered from an error to a warning by un-exporting DEBEMAIL.

Or we could update the maintainer field of backports. But that's up to
the backporters.

[Benjamin Drung (bdrung)]

Wouldn't it be better to tweak dpkg-source to look for "ubuntu", but not for "~ubuntu"?

[Jeremy Bícha (jbicha)]

By the way, what does this mean?

"backportpackage: Switch to ~ubuntu12.04.1-style version numbers instead of ~precise1, to make our version numbers more future-proof."

[Evan Broder (broder)]

We used to generate backport version numbers of the form VERSION_BEING_BACKPORTED~RELEASE_CODENAME1. It worked well at the time because it guaranteed that a backport of the same version to, e.g., natty would have a lower version number than the backport to oneiric, since the n would sort before o. That's important because we rely on the version numbers sorting like that for release upgrade paths with backports to work.

Colin pointed out that this would break down when we ran out of letters and started wrapping around, and suggested that we instead switch to using the version number, which is what backportpackage now does.

Status changed to 'Confirmed' because the bug affects multiple users.

This bug was fixed in the package ubuntu-dev-tools - 0.143
