Finally, I decide to remove this package from my laptop repository, but
end up with the following errors:
git rm -rf git-emacs
rm 'lib/emacs/lisp/git-emacs'
fatal: git rm: 'lib/emacs/lisp/git-emacs': Operation not permitted
We don't say "Operation not permitted" ourselves; it is coming from your C
library's strerror(3) when we got EPERM error back. The reason you get
EPERM can vary depending on your platform and what you did to your
directories yourself, but googling for "Operation not permitted" and
randomly reading a few might give you hints.
