[Bug 1767703] Re: Calling 'apt-install grub-efi-amd64-signed' failed

[aimwin]

Sorry I could not find the old edit link to go and edit my post so I
repeat the part that need modifications/////

My conclusion is Moderator must now file this as real bugs in 18.04

The bugs lies in the 4 parts.

1. It did not detect that we have BIOS mode installations in place,
like the 16.04.4 and older version (I have not tried 17. at all).
So It keep going to install to efi partition which resulted in this error.

2. I belived I did find once or twice in some different configuration that it present the choice at the beginning of the installation process and I chose Bios.
But still got the same result of same errors.
But some how most of time no questions ask at the begging.

3. It should have check if the efi partition exist before it activate the efi installation mode.
I did not have EFI partition on purpose, And It should find that easily by use the program algorithm.

4. At the end error last 2 warning page freezed and stay there until we reboot.
except Lubuntu 18.04 allow us to close the error warning pages.
So even within 18.04 there are bugs for sure. 
Lubuntu did not have this 4th bug while the UBUNTU AND KYLIN HAS.

I hope the Guru will have some clues by now how to find these bugs and
fix it.

Best Regards
