[Bug 1456911] Re: Ubuntu installation/update-grub fail on specific BIOS

[Launchpad Bug Tracker]

This bug was fixed in the package grub2 - 2.02~beta2-26ubuntu3

---------------
grub2 (2.02~beta2-26ubuntu3) wily; urgency=medium

  * debian/patches/uefi_firmware_setup.patch: take into account that the UEFI
    variable OsIndicationsSupported is a bit field, and as such should be
    compared as hex values in 30_uefi-firmware.in. (LP: #1456911)
  * Update quick boot logic to handle abstractions for which there is no
    write support. (LP: #1274320)
