Bug Description

I did the following:

$ bzr co lp:vmbuilder
$ cd vmbuilder
$ bzr merge lp:~mvo/vmbuilder/add-natty
bzr: ERROR: Not a branch: "bzr+ssh://bazaar.launchpad.net/~ubuntu-virt/vmbuilder/0.12/".

This is rather confusing as I have no idea where this references to 0.12 comes from.
Fortuantely jelmer in #bzr gave me the hint that the stacked branch 0.12 might have been
renamed or disappeared and this may cause the error.

The other interessting bit is that I pushed my local "add-natty" branch as lp:~mvo/vmbuilder/add-natty2:
$ bzr push lp:~mvo/vmbuilder/add-natty2
Using default stacking branch /~vmbuilder-dev/vmbuilder/0.12 at lp-57748368:///~mvo/vmbuilder
Created new stacked branch referring to /~vmbuilder-dev/vmbuilder/0.12.

*but* that branch I was able to merge into lp:vmbuilder.

I just reproduced my steps in /tmp and I can easily trigger the error about the 0.12 branch with lp:~mvo/vmbuilder/add-natty. Please let me know if you need more info.

Hm, actually it seems like I get this error now with most (all?) the branches on:
https://code.launchpad.net/vmbuilder

Hm, there is:
https://launchpad.net/vmbuilder/0.12
and it says it points to lp:vmbuilder

While launchpad-code can try to reduce occurrences of missing stacked-on branches (and we already have bugs for that), the issue of the poor error message is not limited to Launchpad, and should be fixed in bzr.

The issue seems to be that lp:vmbuilder is ~vmbuilder-dev/vmbuilder/0.12 rather than ~ubuntu-virt/vmbuilder/0.12

Pointed out on #bzr:
<maxb> mvo: Note the difference between ~ubuntu-virt/vmbuilder/0.12 and ~vmbuilder-dev/vmbuilder/0.12

I added a bugtask against launchpad-code because I would like to see the stacked origin getting fixed. I can currently not merge older vmbuilder branches into trunk. Let me know if there is another/better way to request fixing this. I tried irc as well and I'm happy to submit a RT ticket if that is needed.

Michael, as I mentioned, we already have bugs for fixing the stacked on branch, so we don't need a new one. From the summary, this is a bug about a bad error message, which is a client-side issue.

affects: launchpad-code → null

If you would like us to manually fix a particular branch, ask on IRC or file a Question.
