  • I am also having this problem.. Did you ever find the answer to this?

  • Hello,
    I had this problem today.
    I’m working with a sinatra ruby based application with puma.
    It was because i scale my app doing :

    dokku ps:scale ango web=1 worker=1
    

    but i didn’t configure worker on the Procfile
    So i get the same error than you :

    App container failed to start!!
    =====> myapp container output:
    setuidgid: usage: setuidgid account child
    =====> end myapp container output
    

    What i did to fix this issue is the setup the worker to 0 :

    dokku ps:scale ango web=1 worker=0
    
    

    Hope, it could help you.
