Hey Leo,
Thank you so very much for your suggestion.
We fixed it by doing the following steps:
Run the following SQL command to check the last successful update:
select top 1 * from OrchestratorJob order by LastProcessedDateTime desc;
select top 1 * from RunBookTask order by StartDateTime desc;
Then update their State field from 2 to 1 in both queries like this.
update OrchestratorJob set State = 1 where JobId = 'your_job_id';
update RunBookTask set State = 1, Retries = 1 where RunbookTaskId = 'runbook_task_id';
Now the LCS is showing download retry button, so retry it and update environment.
Once this update is done, we re-updated the environment with the new package uploaded in the assets.
