brew [re]install firefox started to ignore system language and even --language=de

[schwedenmut]

Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match error.

Description of issue

Installing f.e. Firefox via brew install firefox or brew install --language=de firefox ignores the system locale and the manually set German language and installs the default en-US version of firefox. But just to make sure my problem is understood, the cask gets instant so there is no command failing, it's just not doing what I am used to and would expect. I actually didn't find any related changes in the docs/readme/changelog which could explain this behavior.

I checked with two different MacBooks (15"/13") with different but updated macOS Ventura and Monterey.

My locale is set to

LANG="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_CTYPE="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_ALL=

and setting LC_ALL to "de_DE.UTF-8" didn't make a difference during my tests.

Thanks a lot for taking a look into this and for this awesome project 👍.

Command that failed

brew [re]install --language=de firefox, brew [re]install firefox

Thanks for the report. What's the output of brew config? Does setting

export HOMEBREW_NO_INSTALL_FROM_API=1

then reinstalling Firefox help?

[schwedenmut]

hey @carlocab - thanks for your reply and the pointing into the correct direction. With disabling install from API as described above the brew reinstall firefox correctly picks up my language in correctly installs the locale version.

Thanks for letting us know.

I reported this at Homebrew/brew#13794. We should hopefully get this fixed without needing the environment variable soon.
