apport information

** Tags added: apport-collected ubiquity-22.04.17

** Description changed:

  I am using the installer in the released image of Xubuntu 22.04.1
  (jammy). The ubiquity version is 22.04.17.
  
  The system supports UEFI, but this is disabled. /sys/firmware/efivars/
  is absent, and no EFI partition is present. syslog even shows this line:
  
      Oct  2 04:20:23 xubuntu 05efi: debug: Not on UEFI platform
  
  I use the "Something else" option for partitioning, and set up swap, /,
  and /home partitions.
  
  The install then fails with
  
      ==== Unable to install GRUB in /dev/sda ====
  
      Executing 'grub-install /dev/sda' failed.
  
      This is a fatal error.
  
  Here is the relevant excerpt from syslog:
