Error starting for first time

[patrickstanley]

Tried installing the component, but ran into the following error. Running 2021.12.1 inside docker. I am also running Passive BLE monitor integration which work fine, so HA can talk to the bluetooth dongle. Any suggestions?

`This error originated from a custom integration.

Challenge seems to be that inside the alpine docker container, there is no setcap.

`$ docker exec -it home-assistant bash

bash-5.1# whoami

root

bash-5.1# setcap 'cap_net_raw,cap_net_admin+eip' bluepy-helper

bash: setcap: command not found
`

Thanks. I am embarrassed that I didn't find that sooner with the amount of time I spent searching. I knew it would be simple, but I just wasn't getting it. It all works now so thank you again.

For the record, I did the following from within the docker container:

apk add libcap
setcap 'cap_net_raw,cap_net_admin+eip' $(readlink -f $(which python3))
setcap 'cap_net_raw+ep' $(readlink -f $(which hcitool))
