Issue converting mercurial repository to subversion on windows7 64 bit and Ubuntu

Question

I want to convert a mercurial repository into subversion (I know, I know) but the standard answer for this Converting from Mercurial to Subversion doesn't seem to work for me. I have installed tortoiseHg and the svn command line package from collabnet. Any ideas or tips?

D:\work\horizon>hg convert --dest-type svn src horizon-svn --debug --traceback
initializing svn repository 'horizon-svn'
running: "svnadmin" "create" "D:\work\horizon\horizon-svn" < NUL:
Traceback (most recent call last):
  File "mercurial\dispatch.pyo", line 87, in _runcatch
  File "mercurial\dispatch.pyo", line 696, in _dispatch
  File "mercurial\dispatch.pyo", line 472, in runcommand
  File "mercurial\extensions.pyo", line 184, in wrap

  File "hgext\convert\common.pyo", line 318, in checkexit
Abort: svnadmin exited with status 1

And here is the version information:

D:\test\Horizon>hg version
Mercurial Distributed SCM (version 2.2.3)

D:\test\Horizon>

When I try the same on Ubuntu it also fails in a similar way.

mike@mike-virtual-machine ~/repos $ hg convert --dest-type svn ~/Horizon ~/HorizonToSvn -v --debug  --traceback > debug_convert.log

You could try to do the conversion in an Ubuntu virtual machine, maybe it works there. Also, you should file a bug report in the Mercurial bug tracking system, cause this looks like a bug to me. (Obviously not a very often-tested area of code.) — Laurens Holst

Standard answer to today's situation, I suppose, must be "Use hgsubversion for ineraction"

Extended version:

You must transform Mercurial DAG into applicable for Subversion linear history before push
You can create empty SVN-repo as future push-target or (for existing SVN-source), clone SVN-repo into additional repo, pull from it your repo, merge, push
For pushing into empty repo authormap and branchmap maybe have to be prepared by hand
