[Bug 1695562] Re: (/boot/efi not mounted) package shim-signed 1.28+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

Hi Steve,

Thanks for your response.

No, I didn't format the disk; I upgraded to 17.04 with 16.10 running. I
think there is a bug with this kind of upgrade because I didn't have this
problem before. I am only using Ubuntu Mate.
