Bzr import fails with NotImplementedError in broken_remote_exceptions

[Matt Jones]

When trying to get launchpad to import my bazaar code I keep getting errors:

The logs look like this:

I upgraded the branch from format pack-0.92 to 2a using bzr upgrade, and it imported correctly. Is pack-0.92 deprecated?

You can still see the problem on the older branches which I have not upgraded:

https://code.launchpad.net/~workhorsy/rester/rootintootin-0.8.0
https://code.launchpad.net/~workhorsy/rester/rootintootin-0.7.0

[Matt Jones (workhorsy)]

So it looks like pack-0.92 is deprecated:
http://doc.bazaar.canonical.com/development/en/user-reference/other-formats-help.html

Then Launchpad should say that is the reason it was not able to import. And for the user to bzr upgrade to fix the broblem.

Fixed in stable r16170 (http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/16170) by a commit, but not testable.
