Ubuntu 25.10: stty: invalid argument breaks Symfony Console and other CLI tools

[lmadev]

Hi everyone,

After upgrading from Ubuntu 25.04 (Oracular Oriole) to Ubuntu 25.10 (Questing Quokka), I noticed a regression in terminal behavior affecting PHP, Symfony, and other CLI tools that rely on stty.

When running any Symfony Console command (for example php bin/console make:entity), I get this message before the interactive prompt:

Class name of the entity to create or update (e.g. GrumpyKangaroo): > User
stty: invalid argument '500:5:f00bf:8a3b:3:1c:7f:15:4:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0'
Your entity already exists! So let's add some new fields!

Despite the warning, the tool still runs — but input visibility in the terminal sometimes breaks (you can’t see what you type).

This issue happens across different terminals (GNOME Terminal, Tilix, VSCode integrated terminal).
It did not happen in Ubuntu 25.04.

Hi and welcome to Ubuntu Discourse

I moved your topic to support since this is not really a project discussion.

Did you check the release notes for 25.10?

@utkarsh

The Terminal app is now provided by Ptyxis instead of GNOME Terminal.

I don’t know if that change has something to do with it but would be worthwhile investigating.

Hope that helps.

Migration to rust-coreutils in 25.10

We’d like to migrate to rust-coreutils this cycle as a new default. People can revert back if needed. Below are the relevant parts of the internal draft spec. I’d like to upload the changes as soon as possible once the archive is open, probably next week. Mechanisms for migrating Migrating coreutils to a new package is an arduous task, as it is an Essential package which has the requirements that: It must work when merely unpacked, files must not disappear at any point It must not conflict w…

This issue happens across different terminals (GNOME Terminal, Tilix, VSCode integrated terminal).

As per this, it’s more likey related to the rust coreutils (/cc @juliank) and in particular to stty: invalid argument · Issue #8608 · uutils/coreutils · GitHub

I also see “stty: invalid argument '...'” in a new shell when oh-my-zsh prompts to update

[lmadev]

I also use oh-my-zsh, but after switching to Bash, the problem persists
I wonder if it’s possible to install an older version of coreutils, e.g., from Ubuntu 23.04, alongside rust-coreutils
