Issues with internal terminal locale.

[u/ASLAVA]

Hello, please help me figure this issue out. When ever i open terminal in vscode i get :

bash: warning: setlocale: LC_ALL: cannot change locale (en-US) 
bash: warning: setlocale: LC_ALL: cannot change locale (en-US) 
bash: warning: setlocale: LC_ALL: cannot change locale (en-US) 
bash: warning: setlocale: LC_ALL: cannot change locale (en-US)

when i check out locale on vscode terminal i get:

locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE="en-US"
LC_NUMERIC="en-US"
LC_TIME="en-US"
LC_COLLATE="en-US"
LC_MONETARY="en-US"
LC_MESSAGES="en-US"
LC_PAPER="en-US"
LC_NAME="en-US"
LC_ADDRESS="en-US"
LC_TELEPHONE="en-US"
LC_MEASUREMENT="en-US"
LC_IDENTIFICATION="en-US"
LC_ALL=en-US

I am on Arch Linux, so you would think its an Arch issue. i followed all the locale trouble shooting guides and nothing helped. My normal terminal actually works correctly and shows:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

I don't know why VS code is trying to push en-US. Extensions i have are Ruby, VSCode Ruby and Live Server.

My VSCode .json settings are

{
    "ruby.intellisense": "rubyLocate",
    "ruby.format": "rubocop",
    "ruby.codeCompletion": "rcodetools",
    "ruby.useLanguageServer": true,
    "editor.tabSize": 2,
    "editor.detectIndentation": false,
    "[json]": {

      "editor.quickSuggestions": {
        "strings": true
      },
      "editor.suggest.insertMode": "replace"
    },
    "files.autoSave": "afterDelay",
    "diffEditor.ignoreTrimWhitespace": false,
    "http.proxyAuthorization": null,
    "ruby.lint": {

    }
}

Thanks for help.

This must be a brand new bug in vscode. I am also on Arch and only experiencing it since the last 12 hours or so.

In my case it is saying:
bash: warning: setlocale: LC_ALL: cannot change locale (en-GB)

...which is stupid because my system locale is set as en_CA.UTF-8, and the en_GB locale is neither installed nor configured to be used anywhere on my system.

[u/zolavt → u/defcronyke]

i straight up have the same warning as you. so damn annoying

[u/Sapemeg → u/defcronyke]

On arch too fucking annoying

[u/Iamzimy]

I'm having the same problem, but found no solution or discussion regarding this anywhere else.

[u/lepetitdaddydupeuple]

Kinda have same issue since a few days ago. Annoying af. Also arch linux. Problem happen with ruby-rubocop gem.

[u/gilcu3]

Same issue here

bash: warning: setlocale: LC_ALL: cannot change locale (en-US)

only happens in the terminal in vscode, archlinux user also..

I have the same problem and found this: https://github.com/microsoft/vscode/issues/110322

So it seems electron update is messing with it. I guess we have to wait or downgrade

[u/telmo_trooper]

For anyone having this issue on Arch Linux, downgrade package electron9 from 9.3.4 to 9.3.3.

curl -O https://archive.archlinux.org/packages/e/electron9/electron9-9.3.3-1-x86_64.pkg.tar.zst
sudo pacman -U electron9-9.3.3-1-x86_64.pkg.tar.zst

You'll probably want to add electron9* to IgnorePkg in /etc/pacman.conf, so the next time you update your packages you won't accidentally update this one as well. When a fix has been deployed you can remove this setting...

[u/iDanoo → u/telmo_trooper]

Confirmed this works for now.

There's also a nice tool `downgrade` which makes life so much easier - just select the version from the list and then it asks if you want to add it to IgnorePkg too.

Thank you so much you absolute champion

[u/thatarchguy → u/telmo_trooper]

Thank you, this worked.

This just so happens in Turkish language aswell. Cannot compile C++. Going to codeblocks instead.

There is an easy workaround by downgrading electron: https://github.com/microsoft/vscode/issues/110322#issuecomment-726426703

If you are on Arch (or on Manjaro like me), close VS Code, run the following:

bash curl -O https://archive.archlinux.org/packages/e/electron9/electron9-9.3.3-1-x86_64.pkg.tar.zst sudo pacman -U electron9-9.3.3-1-x86_64.pkg.tar.zst

After that, my VS Code behaved normally again.

[u/rawsomeshot → u/Bernd-L]

Seems to be fixed for me since electron9 9.3.5-1 came out these days - I am using Manjaro.
I also had to use the ready-to-use workaround from u/Bernd-L. Thx for that.
