* iTerm2 version: 3.6.4 * OS version: macOS Tahoe 26.0.1 * Host OS version: Ubuntu 25.10 _questing_ ## Detailed steps to reproduce the problem: 1. Using `it2ssh` to connect to a Ubuntu 25.10 Host will fail with a `stty` error. ## What happened: The issue is that Ubuntu 25.10 has moved the default `coreutils` to `rust-coreutils`. The new version of `stty` included in that package does not appear to deal well with the stty commands that it2ssh sends. The error looks like: ``` stty: invalid argument '6900:5:f00bf:8a33:3:1c: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' ``` ## A working solution: In the short term, you can replace stty with the normal GNU version and it2ssh will connect normally. ``` $ apt install gnu-coreutils $ update-alternatives --install /usr/bin/stty stty /usr/bin/gnustty 99 ``` There are a number of open issues with the `rust-coreutils` and `stty` <a href="https://github.com/uutils/coreutils/issues?q=stty">here</a> so this may be the way to go for the time being.
