Public bug reported:
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.
