Bug#882769: Cannot upgrade from Stretch: cp: target '/lib/live/mount/medium/live/vmlinuz.new' is not a directory

[Thomas Goirand <zigo@debian.org>]

Package: live-boot-initramfs-tools
Version: 1:20170623
Severity: serious

Hi,

After booting a Stretch live image, I tried to upgrade it to Sid, and
it fails with this error:

update-initramfs: deferring update (trigger activated)
cp: target '/lib/live/mount/medium/live/vmlinuz.new' is not a directory

Removing the package live-boot-initramfs-tools before the upgrade isn't
even a workaround, it continues to crash.

I need this to be fixed ASAP, as I'm using Live to test OpenStack, and
this is a major blocker to me. I probably will attempt to fix it myself
and NMU the package with no delay if you're fine with that, however,
I'd appreciate help here.

Cheers,

Thomas Goirand (zigo)
