Issue Details

• Electron Version:
  • 9.3.4
• Operating System:
  • ArchLinux 5.9.8-arch1-1
• Last Known Working Electron version:
  • 9.3.3

Expected Behavior

Running the command locale on a vscode terminal should match locale on a terminal. For instance, using the locale fr_FR.UTF-8 the command should output something like:

[someone@somewhere ~]$ locale
LANG=fr_FR.UTF-8
LC_CTYPE="fr_FR.UTF-8"
LC_NUMERIC="fr_FR.UTF-8"
LC_TIME="fr_FR.UTF-8"
LC_COLLATE="fr_FR.UTF-8"
LC_MONETARY="fr_FR.UTF-8"
LC_MESSAGES="fr_FR.UTF-8"
LC_PAPER="fr_FR.UTF-8"
LC_NAME="fr_FR.UTF-8"
LC_ADDRESS="fr_FR.UTF-8"
LC_TELEPHONE="fr_FR.UTF-8"
LC_MEASUREMENT="fr_FR.UTF-8"
LC_IDENTIFICATION="fr_FR.UTF-8"
LC_ALL=

Actual Behavior

The vscode terminal issue a warning repeatedly and the locale output is not correct.

bash: warning: setlocale: LC_ALL: cannot change locale (fr)
[someone@somewhere ~]$ locale
LANG=fr_FR.UTF-8
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=C

To Reproduce

• Go on your favorite Linux distribution
• Install vscode and electron 9.3.4
• Open a terminal in vscode, you will see the warning
• Type locale, you will see wrong output

Additional Information

• If I downgrade electron9 (9.3.4 -> 9.3.3) without touching vscode, the issue is gone.

I suppose this is the same issue as #26443.
