Error "stty: invalid argument" while creating new laravel app or new filament panel

Question

I'm on Kubuntu (25.10) and I just tried creating a new laravel app using the laravel installer laravel new myapp and got this error

In Terminal.php line 114: stty: invalid argument '4500:5:f00bf:8a3b:3:1c:7f:15:4:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0'

new [--dev] [--git] [--branch BRANCH] [--github [GITHUB]] [--organization ORGANIZATION] [--database DATABASE] [--react] [--vue] [--livewire] [--livewire-class-components] [--workos] [--no-authentication] [--pest] [--phpunit] [--npm] [--pnpm] [--bun] [--yarn] [--boost] [--using [USING]] [-f|--force] [--]

So I used composer to install it composer create-project --prefer-dist laravel/laravel myapp and it worked but I got the same error again when I tried to create a new filament panel after installing Filament php artisan filament:install --panels:

RuntimeException 

  stty: invalid argument '4500:5:f00bf:8a3b:3:1c:7f:15:4:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0'

You are hitting a known bug in Kubuntu 25.10’s stty (the utility installed from the rust-coreutils package).

It breaks Laravel interactive prompts with stty: invalid argument ....

Try run:

$ sudo apt install coreutils rust-coreutils- coreutils-from-uutils-

This will install the original coreutils package and remove the rust-coreutils packages.

Then rerun laravel new / php artisan filament:install and it should work without yielding that diagnostic message.

This returns an error: WARNING: The following essential packages will be removed. This should NOT be done unless you know exactly what you are doing! coreutils-from-uutils rust-coreutils (due to coreutils-from-uutils). Error: Removing essential system-critical packages is not permitted. This might break the system.

yes remove the rust-based coreutils variant and reinstall the normal coreutils package.

Silikazi Nov 17 at 12:28

if you are worried use a container / different distro for Laravel commands (e.g. official PHP Docker image, or an LTS Ubuntu VM).

This worked but what does this mean for future updates since now I removed the rust-based utils and reinstalled the original GNU ones?

Silikazi Nov 17 at 12:48

on future firstly package managers donot randomly re-add packages you explicitly removed, unless a future Kubuntu metapackage explicitly pulls them back in as dependencies or recommendations.

@Silikazi: That "coreutils-from-uutils" sounds as if there could be a meta-package to opt-in/out of that, maybe you know more? Just asking, because I looked into it and compared with Opengroup stty utility description and it does not even matches that, so my educated guess would be the maintainers have made this a bit more comfortable?

I had this issue on Ubuntu 25, and running this was able to fix the issue for me:

sudo update-alternatives --install /usr/bin/stty stty /usr/bin/gnustty 100
