# Reporters - Georgios P. Katsikas (UBITECH) # Description Telemetry INT collector was misplaced in the backend git repo. Also, some Python versioning issues prevented proper deployment. ## Deployment environment - Linux Ubuntu server 22.04.5 LTS - MicroK8s (include version and add-ons): - TeraFlowSDN: latest develop ## TFS deployment settings - list of components deployed: context device pathcomp service nbi webui kpi_manager kpi_value_writer kpi_value_api telemetry ## Sequence of actions that resulted in the bug - deploy/all.sh was failing due to python versioning errors ## Document the explicit error - affected component is telemetry-backend - example error: ``` Waiting for 'telemetry' component... error: timed out waiting for the condition on deployments/telemetryservice Failed to deploy 'telemetry' component, exit code '1', exiting...
