Comment 3 for bug 1558438

This bug was fixed in the package grub2 - 2.02~beta2-36ubuntu2

---------------
grub2 (2.02~beta2-36ubuntu2) xenial; urgency=medium

  * debian/postinst.in: (LP: #1558438)
    - fix quoting variables for setup_mok_validation() to account for passwords
      that might have special characters.
    - use printf rather than straight echo to pass values to mokutil.
    - ask the user to confirm password; not just write it once, this will avoid
      issues with typos in the Secure Boot keys.
