--8<---------------cut here---------------start------------->8---
This is GNU Emacs, one component of the GNU/Linux operating system.

GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ V
--8<---------------cut here---------------end--------------->8---

Your version is not that much newer than mine, so it's probably an
