Stamus Packages Error

[Chimney-bit]

Seem to be having an issue with regards to retrieving the stamus packages (selks?) when building the Dockerfile locally. (Seems to operate fine when pulling from Docker Hub).

Get the following errors during 'apt-get update' stage:

W: GPG error: http://packages.stamus-networks.com/selks4/debian stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D2166FA40E9036DC
E: The repository 'http://packages.stamus-networks.com/selks4/debian stretch InRelease' is not signed.

Seems strange that the stamus-packages.list asks for stretch main but constantly retrieves the InRelease. Also, this repo used to operate fine a couple of weeks ago but has only stopped working recently.

My current setup:
Docker version 18.09.7
Docker-compose 1.24
Ubuntu 19.04

hmm this is the old keys think the ones from selks5 should be used.
