OL-1951 — Supervisor could not be installed
OL-1951 · ERR_SUPERVISION_INSTALL_FAILED
What happened
The client could not install the operating-system supervisor (launchd, systemd or Task Scheduler): writing its files failed, or the supervisor refused the registration.
What to do
Read the operating-system error printed with the code, which names the cause: a folder permission, a systemctl failure or a missing user session bus on Linux, or a schtasks failure on Windows. Fix it, then run openlatch system supervision install.
