Package: grub2 Version: 2.02+dfsg1 The completions file for grub2 are being installed into the obsolete directory, /etc/bash_completion.d/, when they should be installed under the default directory, /usr/share/bash-completion/completions.
The reason for this is that the obsolete directory is hardcoded: $ dget http://http.debian.net/debian/pool/main/g/grub2/grub2_2.02+dfsg1-8.dsc $ grep -RnE completion grub2-2.02+dfsg1/ grub2-2.02+dfsg1/debian/grub-common.install.in:5:etc/bash_completion.d I believe that the fix needs to be done in grub2, rather than in bash-completion, as explained in bug report 811496, more specifically, in message 83 [1].
