Log seems truncated.

Something enables sh xtrace (set -x) during update-grub. That’s certainly too verbose log output. Usability issue, yes as proven by this forum thread. But security issue, no.

set -x might for example be set here:

  • /etc/default/grub file
  • /etc/default/grub.d folder
  • /etc/grub.d folder
  • /usr/sbin/grub-mkconfig script
  • /usr/sbin/update-grub

To debug:

sudo sh -x /usr/sbin/grub-mkconfig

and post output here.

Using apparmor-profile-everything? That has a set -x.
