Hi Andrew, Many thanks for prompt reply. The issue was exactly what you described.
I created alternatives for sahara-api, sahara-engine and sahara, and left _sahara-subprocess. This is how juno was working hence I kept the setup same. Now I created alternatives for _sahara-subprocess and it solved the issue.
