This is a recommendation to rebuild some packages with updated debhelper to enable new features, e.g. trigger support.
Please identify the correct package causing this warning and retest the rdepends after that package was fixed.
This issue may be a false positive during upgrade tests, since it can be triggered on an old package before (or while) it gets upgraded.
The commandline to find these logs is:
COMMAND='grep -E "Please rebuild the package|should be rebuilt|should be rebuild|warning: maintainer scripts should not call install-info anymore|called emacs-package-install as a new-style add-on, but has no compat file"'
