“fatal: index file corrupt” keeps repeating in git

The following error keeps repeating even after I’ve tried the recommended:

rm .git/index
git reset

But I still get this error:

error: bad index file sha1 signature
fatal: index file corrupt
fatal: 'git status --porcelain' failed in submodule '[directory path omitted]'

What's wrong? What should I do?

I had that problem, and I tried to fix it with this:

rm -f .git/index
git reset

BUT it did not work. The solution? For some reason I had other .git folders in sub directories. I delete those .git folders (not the principal) and git reset again. Once they were deleted, everything worked again.
