[Bug 1536810] Re: kernel install failed /bin/cp: cannot stat ‘/boot/initrd.img-4.3.0-7-generic’: No such file or directory
Looking at the postinst script, it calls update-initramfs -u and expects
it to do somethin, i.e. create the initramfs.
However, it can choose to not do so, and deffer the update. And thus not
create an initramfs. However, when we are upgrading to a new kernel
image, we expect to generate an initramfs cause we will be fixing
symlinks and so on right after.
I have linux-image-4.3.0-6.17 installed, via linux-virtual metapackage
on an old cloud image (see my private fileshare). And upgrading that to
xenial/release 4.3.0-7.18 fails like so:
ubuntu@ubuntu:~$ dpkg -l | grep linux

My solution to the problem is to force update-initramfs to create an
initrd when the linux-image upgrade scripts expect to have that to
happen. See the attached patch.
