i have tried:

sudo apt-get update sudo apt-get autoremove 

and same errors.

dpkg list is:

if linux-signed-i 4.4.0-45.66 amd64 signed kernel image generic iu linux-signed-i 4.4.0.45.48 amd64 signed generic linux kernel image

dpkg -s linux-signed-image-4.4.0-45-generic package: linux-signed-image-4.4.0-45-generic status: install ok half-configured priority: optional section: utils installed-size: 21 maintainer: canonical kernel team <kernel-team@lists.ubuntu.com> architecture: amd64 source: linux-signed version: 4.4.0-45.66 depends: sbsigntool, linux-image-4.4.0-45-generic (= 4.4.0-45.66) description: signed kernel image generic kernel image generic. version of signed canonical's uefi signing key. built-using: linux (= 4.4.0-45.66)

i have tried reinstall packagebut same error:

sudo apt-get -f install linux-signed-image-4.4.0-45-generic ... setting linux-signed-image-4.4.0-45-generic (4.4.0-45.66) ... cp: cannot stat '/boot/vmlinuz-4.4.0-45-generic': no such file or directory dpkg: error processing package linux-signed-image-4.4.0-45-generic (--configure): ...

so have problem in linux-signed-image-4.4.0-45-generic half-configured because there no /boot/vmlinuz-4.4.0-45-generic file. guess happen after fixed uefi boot problem using boot-repair. how can solve it? in advance

short version of answer;
boot selected kernel know have been running well, check output of

$ uname -a

make sure keep version of kernel (linux-image... above) ,

$ sudo apt-get purge ...

... on packages list other version numbers, including 4.4.0-45 version (i'm assuming cannot run/booted).

when have purged unused ones, should able re-install 4.4.0-45, boot , optionally remove used one.

i'd recommend keep at least 1 version other latest, (that know work) safety/backup/repair...

why?
guess have run out of space on /boot ... or possibly somewhere else - above should free space in relevant places, regardless of problem is.
