package shim-signed 1.32~16.04.1+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

I have dual booted Windows 10 and Ubuntu.

I also have an issue that sometimes when shutting down or rebooting Ubuntu doesnt shut down and hangs on shutdown screen and I have to force shutdown.

This errors popped on startup. I have no idea what they are about, probably force shutdowns caused them.
