Repo format conversion strategy?

[Doug Lee]

Update on my repo conversion problems:

For the below push operations, I am using brz 3.3.17 and Python 3.13.3.

I have converted over 200 brz/bzr workspaces to Git successfully using the remote-vzr approach (fastimport very often died with missing-file errors). I have three or four repos so far that refuse to cooperate though.

Using "bzr push --lossy" does successfully create a Git repo, but "git fsck" fails with messages like this:

broken link from    tree d9bdc6dfd71df839730aee3cfea2dd9d28a8943e
              to    tree dc9fca88268e3cd15cdec53564a33d288c17a173
dangling tree 4b825dc642cb6eb9a060e54bf8d69288fbee4904
missing tree dc9fca88268e3cd15cdec53564a33d288c17a173

I also still see no tags in the Git repo.

Unfortunately these are not public repos, but I wonder if there is anything I can do to either rescue them or help brz address the issues I'm seeing.

Ah, got me!  Ubuntu has not updated that package but I forgot to look for updates outside of apt.
