Comment (by dcf):

 I encountered this problem again today during `Building sandbox-linux for
 jessie amd64`. I tried applying the following workaround and it seems to
 work. The problem seems to be related to `linux-image-xxxx` trying to
 upgrade itself during `dist-upgrade` while `grub` is not installed, which
 causes the post-installation script to fail. My idea was to ensure that
 `linux-image-xxxx` is upgraded before removing `grub` and doing `dist-
 upgrade`.
