[Bug 1067659] Re: ubiquity removes linux-signed during installation cleanup preventing (some) secureboot machines from booting

[Colin Watson]

Now in quantal-updates:

ubiquity (2.12.15) quantal-proposed; urgency=low

  * Make sure not to remove the signed kernel if we need it (LP: #1067659).
  * Copy the signed kernel from /cdrom/casper/vmlinuz.efi.signed.
    /cdrom/casper/vmlinuz needs to remain unsigned to avoid breaking
    checksums.

** Changed in: ubiquity (Ubuntu Quantal)
       Status: In Progress => Fix Released

Bug description:
  The desktop images properly contain both unsigned and signed kernels and boot from the signed one.
  One would expect the installer to keep the signed image on secureboot systems and remove the unsigned one, however it's currently doing the opposite leading to non-bootable systems for those requiring the kernel to be signed.
