"Koha-zebra --start" --> "koha-start-zebra" in line 60 "koha-zebra --stop" --> "koha-stop-zebra" in line75 "koha-zebra --restart" --> "koha-restart-zebra" in line 88 gcb Sigh... And so to bring this thing almost full circle, I started digging, trying to understand why the koha-common service wasn't starting as expected. Going back to the /etc/init.d/koha-common script and comparing 17.05.10 to 17.05.11...at least part of the problem was staring back at lines 26 & 27. # Exit if the package is not installed [ -x /usr/sbin/koha-zebra ] || exit 0 WAIT!!! Wasn't I just told there is no command "koha-zebra" till 18.05??? 1. Change the command to "koha-start-zebra" 2. Restart the OS 4. koha-common is now running (sudo service --status-all) 5. And the koha directories and sub-directories under /var/run have been created as expected I'll try this with my production machine tomorrow and, hopefully, get it updated before 18.05 is released... gcb
