I can reproduce this, not sure why. I have modified my ssh environment so that it is not the default. But I do see a similar error message, using ssh from stable Debian 11. [david@kablamm ~]$ ( bash -cu : ) [david@kablamm ~]$ ssh kablamm Linux kablamm 5.10.0-16-amd64 #1 SMP Debian 5.10.127-2 (2022-07-23) x86_64 Last login: Sat Aug 27 17:00:13 2022 from 10.1.1.2 [david@kablamm ~]$ ( bash -cu : ) /etc/bash.bashrc: line 7: PS1: unbound variable [david@kablamm ~]$ So hopefully someone who understands how ssh interactive session interacts with bash can explain this to us now :)
