Git fatal: Reference has invalid format: 'refs/heads/master

Question

I am using Dropbox to sync a git repository, but now when I try and push I am getting an error:

fatal: Reference has inval         


        

Answer 1

For me it was giving error: fatal: Reference has invalid format: 'refs/tags/r0.2:3'

You can go to /.git/packed_refs file and delete the line for refs/tags/r0.2:3

Then it started working. But why it happened in the first place I don't know.
