Anyone has ideas why I get this error and what exactly it means?

This appears to be just the typical message when error occurs in worker process (in my case import error)

[AbstractMonkey]

If you don't mind, how did you fix this? I am getting the same error.

[ikamensh]

This is not the actual error, its just a hint that there might be an error (seems to be also sometimes caused by parallel processes, even if all errors are fixed.) Go to tmux and then to worker process (tmux -a -> Ctrl-B -> 1(number uncertain, see on the bottom of the screen)), there you might see the actual problem message.

[EMCP]

in this case :

$ tmux a
// screen popped up, hit CTRL-B
// nothing happened, then hit 1

read the error message and you will see

no module ... govnc

you need to install goVNC as per instructions found here https://github.com/openai/go-vncdriver
