I’ve been trying to upgrade my Docker image with some newer packages (not Python 3 yet). I’m building on top of `balenalib/rpi-raspbian` and I’ve had to add a few extra packages that I didn’t need to install with the old `resin/rpi-raspbian` image. I’ve got the build completing successfully, but I get this error when I start Mopidy.

```
ERROR Error during Last.fm setup: NetworkError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:727)

```

What am I missing? I’ve got the latest `apt install ca-certificates` and `pip install certifi`.

Thanks.

I worked it out. You have to run:

```auto
update-ca-certificates --fresh

```
