I'm on linux ubuntu 14.04 lts and I use Mercurial Distributed SCM (version 3.3.2). I try to unbundle a mercurial hg bundle made on Mac osx with command line:
hg unbundle XXX.hg
abort: XXX.hg: unknown bundle version 20
Does anyone have a clue what is going on? Google research has not been providing much informations about that.
I had to add type='bzip2-v1' to the bundle call
from mercurial.commands import bundle
bundle(ui, repo, tmpfile.name, dest=None, base=(parentc.rev(),), rev=(c.rev(),), type='bzip2-v1')
It looks like mercurial introduced a new version of their bundle module somewhere around 3.2, according to:

Your version should have support for bundle2, but there may be some problems unbundling from newer versions of mercurial.
