I have found an alarm sound that I would like to use with Home Assistant. I am running Hassio on Ubuntu, and are having trouble my moving the file from the host to the docker.
I am pretty new to Linux so I have tried:
sudo docker cp ./Downloads/alarm_sound.mp3 49c9XXXX:/www/alarm_sound.mp3
I then get the error “No such container:path 49c9XXXX:/www”.
So I am obviosly doing something wrong
