I'm not sure how to diagnose this issue further. I recently did a brew upgrade of a lot of stuff, one of which was byobu and it fails to even startup spitting out this as the error:

^[[?62;4c[exited]

Obviously the upgrade could have installed a dependency that messed things up as well. Any recommendations of where to look? Or what steps to take to root cause the problem?

I tried exporting this variable first which did not change the outcome:

export BYOBU_RUN_DIR=$HOME/.byobu/run/

Running tmux does start fine, but not byobu. Any other help is appreciated. If you need me to include any other info let me know.

Byobu version:

byobu --version
byobu version 5.133
tmux 3.1

Mac version:

10.15.4 Catalina

There was a version mismatch issue. It turns out the tmux I was defaulting to was an old version, not the one showing when running byobu --version, but one installed by a very old oh-my-zsh plugin. Once I removed the plugin so it pointed to the correct tmux later version everything worked again.

Any tmux command I ran said something like tmux server version is too old for client which led me to run which tmux which pointed to the old, incorrect version.

    For some reason, for me I got that error whenever I tried to paste (with `p`) in nvim. I was getting super mad, when I found this, restarted tmux (which I had just upgraded with brew), and gained a renewed appreciation for the mysterious workings of my dev environment. – Fábio Santos May 08 '20 at 22:53
