[Bug 1738525] Re: 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

Hi Steve,

Thank you for your response, yes you are right that I was not doing a
fresh installation, instead I was overwriting the existing Ubuntu 14.04
installed on my system, keeping apps and documents and settings as it
is, that means, not erasing the previously installed Operating System.

I think part of the problem was my BIOS settings which had boot type set
to UEFI instead of Legacy, I later changed it to Legacy and it
successfully installed xUbuntu 16.04 in the second attempt.

Although I did not lose any documents and settings but because of the
unsuccessful first attempt I lost my apps, which I had to reinstall
after my system got ready :o(

If BIOS settings is the problem then installation should halt at the
very beginning and compel the user to correct it, instead of going ahead
with it and exit with an error leaving an unclean installation and loss
of user apps.
