12.04.2 incorrect file name signed efi amd6.deb

There is no log. It is just a wrong file name in the install ISO.

It is not a file I use as it is UEFI secure boot & I only have ISO. But file is still wrong.

The bug is a misnamed file in the uefi installer for 12.04.2, causing installations to fail. Therefore, a log cannot be collected.

I cannot verify this while looking at the contents of the 12.04.2 ISO images on the master server. Exactly which URL did you download the image in question from?

I downloaded copy from this mirror:
http://mirror.anl.gov/pub/ubuntu-iso/DVDs-Ubuntu/12.04.2/

That has a 14-Feb-2013 date.

Many users in Forum said they could not boot liveCD with secure boot on. I always have said to turn if off. Is this part of the reason?

It now looks like in 12.04.3 that both 6 and 4 are missing from end of file name. The change from 3.9 to 3.10 added a character, so one more was dropped from end of file.
Seems like an issue with file name length on ISO.
Original file on server is probably correct.

This user found more issues and created a perl script to rename files correctly.

In "/pool/main/g/grub2-signed" there is a file named: "grub-efi-amd64-signed_1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd.deb"

At the end of the file name 2 characters are missing. File should be named: "grub-efi-amd64-signed_1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd64.deb"

Bug in version ubuntu-12.04.3-desktop-amd64

Oddly, the filename appears fine when the iso is mounted under linux:

$ sudo mount -o ro -t iso9660 ubuntu-12.04.3-desktop-amd64.iso /mnt
$ ls -l /mnt/pool/main/g/grub2-signed/
total 479
-r--r--r-- 1 root root 489626 Jul 22 16:43 grub-efi-amd64-signed_1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd64.deb

But the last two characters before the extension are dropped when the iso is mounted under windows:

F:\>dir \pool\main\g\grub2-signed
 Volume in drive F is Ubuntu 12.04.3 L
 Volume Serial Number is 8BB6-BA54

 Directory of F:\pool\main\g\grub2-signed

2013/08/20 20:08 <DIR> ..
2013/07/22 16:43 489 626 grub-efi-amd64-signed_1.9~ubuntu12.04.4+1.99-21ubuntu3.10_amd.deb
               1 File(s) 489 626 bytes
               2 Dir(s) 0 bytes free

A difference in iso filesystems perhaps?
Someone with knowledge of iso should probably look at this.

I have a few more details to share.

Mounting the iso under windows 8 displays the same incorrect filename, as does burning the iso to physical media under windows 7.

So to me, it would appear that anyone unlucky enough to use the ubuntu-12.04.3-desktop-amd64.iso under windows 7/8, whether it be to:
a.) physically burn it to disc;
b.) mount it virtually;
c.) create a USB boot system from it
would be unable to successfully install ubuntu 12.04.3 LTS on an UEFI booted system.

During installation of grub, the installer throws the error "'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot."

Because the .deb file is misnamed, the following is reported in syslog during installation:
Dec 4 17:41:36 ubuntu ubiquity: E: Unable to locate package grub-efi-amd64-signed

Workarounds:
===========
If you are creating a bootable USB on Windows 7/8, rename the misnamed file after the USB has been written so that the installer does not error out during installation.

Alternatively, since the file is not misnamed in linux, using the iso to burn a USB boot system from within linux will also likely work.

From what I can gather so far, Boot-Repair seems to be the current mechanism used to resolve problems that result from this, since Boot-Repair first removes grub and then re-installs it.
WARNING: (For those of you that may have arrived here from a Google search) Boot-Repair downloads the grub packages from the Internet, so be sure to have a fully functioning Internet connection if you use this method. If Boot-Repair doesn't find an Internet connection, you will be warned that your system may be left in an unbootable state. Heed this warning, because while apt will happily remove grub without one, it cannot download and re-install grub without a connection to the Internet.

Orginal error was in ISO itself.

Above error seems to be just when written with certain tools that file name is too long to be converted from ISO correctly.

Fair enough.
I came across this while troubleshooting a problem that I later discovered to be reported by bug https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1252255 and rather than repeat what I have found over there, I earlier posted a link there back to this bug.

Hopefully what I have found proves useful to resolving that error for others, so I'll leave it at that.
