I'm using the SVN to Git migration guide:
So far everything has gone well. The Git repository was created and I have synchronized several times to keep the repository up to date with SVN.
However, today I am unable to syncronize and unfortunately I am not yet knowledgable enough about Git to understand what might cause this error.
I ran 'git svn fetch' successfully, but then when I tried to rebase using the Attlassian SVN migration scripts I got the following error. Is this a bug with the Atlassian SVN migration scripts?
$ java -Dfile.encoding=utf-8 -jar ../svn-migration-scripts.jar sync-rebase fatal: ambiguous argument 'heads/(detached from 22ff5b8)': unknown revision or path not in the working tree.

Looks like the migration scripts aren't handling the case where you are in an "detached head" state (ie. you're not on a branch). What branch were you on when you ran sync-rebase? If you checkout master and run the scripts again does it work?
