Laravel Installer crashes on Ubuntu 25.10 due to stty output format

[09dian]

Installer Version

Laravel Installer 5.15.0

Description

Problem

On Ubuntu 25.10, running:

laravel new project

causes the Laravel Installer to crash when the interactive starter-kit prompt appears. The error is:

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

This happens because Ubuntu 24.04+ returns a different stty -g output format, and the Installer tries to execute it without validation, causing the terminal restore step in src/Console/Terminal.php to fail.

Steps to reproduce

1. Fresh Ubuntu 25.10 install
2. Run:

laravel new test

3. When the starter-kit prompt appears, the installer exits with the error above.

Expected behavior

Installer should gracefully handle unsupported stty formats and not crash.

Environment

Ubuntu 25.10
PHP version: (paste output of `php -v`)
Laravel Installer version: (paste output of `composer global show laravel/installer`)

stty -g output:
(paste output)

stty -a output:
(paste output)

echo $TERM
uname -a

Notes

This only happens in interactive mode. Running:

laravel new test --no-interaction

works normally.
