Does it work if you fully close tmux and try again? (e.g. killall -9 tmux / killall -9 /usr/local/bin/tmux / killall -9 /usr/bin/tmux?)
That fixed it for me.
\nFrom tmux/tmux#4699:
\n\n","upvoteCount":1,"url":"https://github.com/tmux-python/tmuxp/discussions/995#discussioncomment-15116950"}}}Note that it is very important to restart tmux entirely after upgrading. This is particularly important with this release because one of the libraries that tmux uses changed its protocol. If you see this message when you try to attach it probably means you forgot to restart tmux:
\n\nopen terminal failed: not a terminal\n

tmux 3.6 and tmuxp 1.57 on Ubuntu 24.04 (I use pixi package manager to install). I get this crash which I didn't have before. Happens on multiple systems. Reverting to old versions (system versions from Ubuntu, tmux 3.4 and tmuxp 1.38) and don't see the crash. |

Moving this to a discussion - this looks tmux 3.6 related and I think we have a workaround |

@tony -- thanks for the feedback, indeed tmux 3.6 is failing by itself, thus not tmuxp specific. I did a pkill for all tmux processes but this doesn't fix it for me. I will investigate on my system a bit more, but at least using |

Thank you! Fine to take up a new issue if you come back with more information if you find it's tmuxp related. Aside: It's worth investigating if |

I tried to update to tmux V3.6a and the latest tmuxp (V1.62) but I am having similar crashes: tmux itself is working again, and I've tried to pkill tmux before running tmuxp after the update... |

I think this should be a new discussion rather than continuing the original thread. tmux 3.6a was reported upstream as fixing the earlier terminal protocol issue (the The failure mode appears different now:
That suggests this is no longer the original tmux 3.6 upgrade problem. If you open a new discussion, please include:
Additionally:
That should let us narrow down whether this is tmuxp, libtmux, or a tmux 3.6a regression without conflating multiple issues. |
