ERROR: exceptions.AttributeError: 'KnitPackRepository' object has no attribute 'revision_parents'

[linas]

Was attempting a 'bzr rebase', against a repo in launchpad.
This has always worked till today. The differences are:

-- today, I'm running Ubuntu 8.10 instead of Ubuntu 8.04
-- there's a conflict between a file in the main repo, and one of my files.

I'm pretty sure I'd done rebase in the past with file conflicts, and it
worked. I'm assuming the new bzr in ubuntu 8.10 is not compatible
with the older rebase ??

Never mind. Upgrrading to rebase version 0.4.2 makes this bug go away. However, Ubuntu 8.10 is currently shipping with the old version of rebase, and so this bug will bite ubunutu users ... anywone know how to report a distro bug ??

[Sean Stoops (brutimus)]

I can confirm that I experienced this exact same behavior. Same software versions it seems (Ubuntu 8.10, python 2.5.2, and BZR 1.6.) After manually upgrading bzr-rebase to 0.4.2, all was back to normal.

[Sean Stoops (brutimus)]

Regarding this bug in the Ubuntu package. bzr-rebase 0.4.2 is slated for Jaunty (9.04), but I would think this warrants a bugfix in Intrepid (8.10). I just don't know what it takes to get package updates tested and pushed out to a particular distro version.

[linas (linasvepstas)]

If the fix has been released, then it hasn't yet bubbled over to the package servers, which are still serving up version 0.3, not version 0.4. So, for example:

The fix is in Jaunty, which has bzr-rebase 0.4.2.

[linas (linasvepstas)]

Bug was reported for Intrepid, not for Jaunty -- a fix is needed for Intrepid. The current status is that the "bzr-rebase" package is broken/inconsistent in Intrepid. Need a 0.42 package for Intrepid, since the current bzr-rebase is not compatible with bzr in Intrepid. Jaunty has nothing to do with it :-)

[Jelmer Vernooij (jelmer)]

this doesn't have anything to do with Bazaar, at least not *upstream* Bazaar.

[Jelmer Vernooij (jelmer)]

I've now nominated this for release in intrepid.

[linas (linasvepstas)]

OK, thank you.
