Bug Description

Hi! If I install Lucid (daily build - 30 march 2010) in Asturian language only 1 entry appears in the Grub menu! I lost others boot menu entries! http://img534.imageshack.us/img534/3774/asturiangrub.jpg

This could happen in another language that can be use an apostrophe in the translations for "Loading Linux %s ..." (Maybe too in another string):

Best regards.

Hi! I did some test (I link some pictures):
- English installation: Grub OK
- Spanish installation: Grub OK http://img696.imageshack.us/img696/4391/spanishgrub.jpg
- Galician installation: Grub OK http://img534.imageshack.us/img534/8123/galiciangrub.jpg
- Asturian installation: Grub WRONG http://img534.imageshack.us/img534/3774/asturiangrub.jpg

I change the line in /boot/grub/grub.cfg in the asturian installation:
set lang=ast
to
set lang=en
But same result :(

I attach to this email my grub file in asturian installation.

Do you need anything more? Any idea, please?
Thanks in advance! Marcos.

I just download the asturian .po file from GNU:
http://translationproject.org/PO-files/ast/grub-1.97+20100124.ast.po
I create the .mo file and save in /boot/grub/locale
Equal result :( Grub only have 1 entry.

summary: - Asturian instalation. Wrong Grub: Only 1 entry in Grub for 2 OS.

I can confirm this bug for "ast" language. (Maybe the 3 letters code are doing the grub crashes)
This bug deletes all the older entries for other OS in the computer. It kills the possibility to boot another OS, or recovery mode

Hi! I found the problem! :D
The apostrophe in the line " echo Cargando'l Linux 2.6.32-18-generic ..." breaks the secuence of grub.

The second entry in grub.cfg boot menu (attachment to this bug before), breaks that appears the next lines in boot menu:
menuentry "Ubuntu, con Linux 2.6.32-18-generic (mou recuperación)" --class ubuntu --class gnu-linux --class gnu --class os {
 recordfail
 insmod ext2
 set root='(/dev/sda,5)'
 search --no-floppy --fs-uuid --set e0cf9b7c-bdae-4659-8165-7294447c1edf
 echo Cargando'l Linux 2.6.32-18-generic ...
 linux /boot/vmlinuz-2.6.32-18-generic root=UUID=e0cf9b7c-bdae-4659-8165-7294447c1edf ro single
 echo Cargando discu RAM inicial...
 initrd /boot/initrd.img-2.6.32-18-generic
}

I searched the string "Cargando'l" in the FreeDesktop translations
http://translationproject.org/PO-files/ast/grub-1.97+20100124.ast.po
and in Launchpad grub translations:
https://translations.launchpad.net/ubuntu/lucid/+source/grub2/+pots/grub/ast/+translate?batch=10&show=all&search=cargando%27l
and I didn't found this string :O

Cheers!

Put this lines works fine:
echo Cargando\'l Linux 2.6.32-18-generic ...
echo "Cargando'l Linux 2.6.32-18-generic ..."
The echo command view the apostrophe as start of string, and not find the end, and all break until the end in the grub config file.

Hi!
We changed by the moment the string for:
echo Cargando Linux 2.6.32-19-generic ...
and in Ubuntu 10.04 beta2 the menu boot is ok.

But for the future, or other languages, that use this apostrophe, the bug will appears ;)

Best regards!
