I'm not sure what has happened, but this command used to work up to now. I have a branch named refactorizacion checked out. If I run the command git fetch, it seems to work fine (no error is shown), but if I run git fetch origin refactorizacion:refactorizacion, it gives me the following error:
fatal: Refusing to fetch into current branch refs/heads/refactorizacion of non-bare repository
Unexpected end of command stream
This is also causing the Team > Synchronize Workspace command of egit in eclipse to show an error:
Fetch operation failed
Synchronization will be continued based on data that are currently in repository.
You can disable fetching changes before synchronization in preferences: Team > Git > Always launch fetch before synchronization
