It seems that there is already a rebase-merge directory, and
I wonder if you are in the middle of another rebase.  If that is the
case, please try
	git rebase (--continue | --abort | --skip)
If that is not the case, please
	rm -fr /home/vlad/privly_forked/privly-chrome/.git/rebase-merge
and run me again.  I am stopping in case you still have something
valuable there.
