Summary: grub2-setpassword only work when locale is C

Fixed In Version: grub2-2.02-0.34 Doc Type: Bug Fix
Doc Text:
Cause: Alternate locales translate the output from CLI tools. Consequence: Searching for proper output in the shell script failed because of the translation; thus grub2-setpassword would fail because it put the wrong string into the password file. Fix: Set Locale for that specific call in the shell script to ensure the output is what we expected to parse. Result: grub2-setpassword works

Description Michael S. 2015-12-25 17:15:13 UTC
Description of problem:
I tried to use grub2-setpassword today. But it did generate a incorrect configuration file. It seems the script is removing the output of grub2-mkpassword using sed, but not taking in account potential translation. So it should be run with LC_ALL=C as variable.


Version-Release number of selected component (if applicable):

# rpm -q grub2-tools
grub2-tools-2.02-0.33.el7_2.x86_64


How reproducible:

each time

Steps to Reproduce:
1. LC_ALL=fr_FR.utf8 grub2-setpassword
2. enter password twice

Actual results:

# cat /boot/grub2/user.cfg
GRUB2_PASSWORD=Entrez le mot de passeĀ : 
Entrez de nouveau le mot de passeĀ : 
Le hachage PBKDF2 du mot de passe est grub.pbkdf2.sha512.10000.9AACE61E4541D7935629D4DE69


Expected results:

# cat /boot/grub2/user.cfg
GRUB2_PASSWORD="grub.pbkdf2.sha512.10000.9AACE61E4541D7935629D4DE69"


Additional info:

The workaround is quite easy:

  LC_ALL=C grub2-setpassword

Also, even if the locale is set to a foreign language, the prompt will not change. And make sure to use a locale where grub2 is translated to, otherwise, it will work fine.
