[EDIT: This was user error on my part but I am leaving post in case someone runs into same problem. The error was my colleague set up the virtual machine and I misunderstood him. I thought he had set up a base Debian8 install when in reality he was using the 64-bit XiVO Server ISO. Therefore, I should been IncrediblePBX13-XiVO2.sh but instead was using IncrediblePBX13-XiVO1.sh ] **** Original Post Below ***** I have just tried the beta installer script IncrediblePBX13-XiVO1.sh on a newly built Debian8 amd64 VM. The install is unable to complete because I get this in the xivo error log when trying to start the xivo-agentd service: Code: 2016-06-29 03:50:57,790  (ERROR) (xivo_agent.bin.agentd): undefined environment variable XIVO_UUID 2016-06-29 03:50:57,790  (CRITICAL) (root): XIVO_UUID environment variable is not set Traceback (most recent call last): File "/usr/bin/xivo-agentd", line 5, in <module> main() File "/usr/lib/python2.7/dist-packages/xivo_agent/bin/agentd.py", line 129, in main set_xivo_uuid(config, logger) File "/usr/lib/python2.7/dist-packages/xivo/config_helper.py", line 143, in set_xivo_uuid config['uuid'] = get_xivo_uuid(logger) File "/usr/lib/python2.7/dist-packages/xivo/config_helper.py", line 138, in get_xivo_uuid raise UUIDNotFound() The log entry is made when executing the python script which causes all the subsequent xivo components to fail.
