Try the same set of steps without elpa-helpful, and the upgrade still fails with Install emacsen-common for emacs emacsen-common: Handling install of emacsen flavor emacs >>Error occurred processing /usr/share/emacs/site-lisp/debian-s tartup.el: File error (("Doing chmod" "Operation not supported" "/usr/share/emacs/site-lisp/debian-startup.elc90iTVh")) At this point dh-elpa is not involved. It seems most likely to be an Emacs 28 bug, but I guess it could also be an issue with emacsen-common.
