[Bug 1922315] [NEW] Ubuntu 21.04 Beta Installer - Error Installing grub-efi-amd64-signed

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Release:  
Description:	Ubuntu Hirsute Hippo (development branch)
Release:	21.04


Installing Ubuntu 21.04 Beta and installation process executes as expected.  At the end of the installation receive a pop up as below:

Title:  Error installing grub-efi-amd64-signed
Body:  installed grub-efi-amd64-signed package post-installation script subprocess returned error exit1.

After clicking OK, get another pop up as below:

Title:  An error occurred while installing packages:
E:Sub-process /usr/bin/dpkg returned error code (1)

The body of the second pop up is to much to type, but says "More details
may be found in /var/log/syslog".  I found the entries below in
/var/log/installer/syslog and believe them to be from the error:

I have pictures of the two popup windows if needed.
