Title:
  rust-based coreutils stty is incompatible with Symfony Console
  (Laravel installer) interactive mode

Status in rust-coreutils package in Ubuntu:
  New

Bug description:
  On Ubuntu 25.10, the default rust-based coreutils (coreutils-from-uutils)
  provides an stty implementation that is incompatible with applications using
  Symfony Console's terminal capability detection.

  Running interactive CLI applications (e.g. `laravel new`) fails with:

    stty: invalid argument '4500:5:f00bf:8a3b:...'

  This occurs even when:
  - running in a real TTY (/dev/pts/*)
  - TERM is correctly set (xterm-256color)
  - locale is UTF-8

  Replacing coreutils-from-uutils with coreutils-from-gnu immediately resolves
  the issue.

  Expected result:
  Interactive CLI applications using stty (via Symfony Console) should work
  with the default Ubuntu coreutils implementation.

  Actual result:
  stty fails with "invalid argument", breaking interactive CLI programs.

  Workaround:
  Replace rust-coreutils with GNU coreutils:
    sudo apt-get install coreutils-from-gnu coreutils-from-uutils- \
      --allow-remove-essential

  Additional notes:
  This appears to be a compatibility gap in the rust stty implementation
  regarding termios flag handling.
