Unable to determine upstream SVN information from HEAD history

Question

Why do I get this error message?

Answer 1

I got this message because I used a FQDN for the git svn init command but the pre-existing git-svn integration was using just the hostname.

E.g. grep git-svn-id showed:

git-svn-id: svn://host/repo/...

But I did:

git svn init -Ttrunk svn://host.domain.com/repo

(We have a machine that regularly syncs a git repo with svn, then everyone else has git config --add remote.origin.fetch refs/remotes/*:refs/remotes/* to fetch down the svn synced branches.)
