The error in your log is:

Setting up shim-signed (1.28+0.9+1474479173.6c180c6-1ubuntu1) ...
Instalando para plataforma x86_64-efi.
grub-install: error: no se puede encontrar el directorio EFI.

Why is /boot/efi not mounted on your system? This must be mounted at package upgrade time in order to install the new versions of the bootloader.
