When running byobu-launcher-install on a new machine (which hasn't run byobu yet), it fails with the following message:
touch: cannot touch `/root/.byobu/disable-autolaunch': No such file or directory
If you start buyobu first, quit and than run byobu-launcher-install, it works fine.
The issue seems to be in byobu-launcher-uninstall. Please find patch attached.
