This issue should be fixed now with updated docker files. Please try again.

@nshmyrev I think this is because of default python on Debian 10 is 3.7 and we must install python3.8 in Docker or change the Debian version. https://github.com/alphacep/vosk-api/issues/294#issuecomment-726352352 https://github.com/alphacep/vosk-server/blob/c5148900586c9a325592ff5b7f8c57bf2b6e46eb/docker/Dockerfile.kaldi-vosk-server#L1

@lalimili6 You do not need 3.8 anymore, now Vosk works with any python version. The information in the link is outdated.
