Public bug reported:
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.
