Public bug reported:
I just did an upgrade and rebooted, and upon loading the kernel grub
presented me with a "double free" error. It was doing this no matter
what kernel I tried to boot, including kernels which were booting fine
before. Out of desperation I disabled secure boot in the bios and the
kernel loaded and booted without error. When I turned secure boot back
on the error came back.
It's likely that none of kernels I have installed have a valid
signature, since I generally install test builds before uploading
kernels, so maybe that's related.
