Description

Packages in question:

Whonix

The postinst script of these packages should call update-grub. Otherwise these packages have no effect before a kernel upgrade triggers or the user manually runs it.

Debian has no update-grub trigger yet:

Done for #grub-screen-resolution package…
run update-grub during postinst so package takes effect right after installation - https://phabricator.whonix.org/T377:
https://github.com/Whonix/grub-screen-resolution/commit/b03aea8ff3a2ad28ec1bec7dba3d4a58e55cceda

Can be easily replicated for the #grub-enable-apparmor and #grub-verbose-output package. Just waiting for potential comments on this.

Anyone has any suggestions on the error message when this fails? (@bnvk, @mfc, @memorylost)

      echo "$DPKG_MAINTSCRIPT_PACKAGE $DPKG_MAINTSCRIPT_NAME ERROR: Running \
'update-grub' failed with exit code $?. $DPKG_MAINTSCRIPT_PACKAGE is most \
likely only the trigger, not the cause. Unless you know this is not an issue, \
you should fix running 'update-grub', otherwise your system might no longer \
boot." >&2

(It fails open, i.e. package installation will succeed. It’s just supposed to be a warning in case this fails.)
