Hi Brooklyners. Just noticed that the Brooklyn master build is consistently failing. Took a quick look and it turns out our docker image is somehow screwed up. We are using the base `maven:3.6.3-jdk-8`, which is based on Ubuntu stretch.
The first instruction in our dockerfile[1] is `apt-get update` which fails with the following error: ``` root@2b191031fcee:/# apt-get update Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB] Get:2 http://deb.debian.org/debian buster InRelease [122 kB] Get:3 http://deb.debian.org/debian buster-updates InRelease [49.3 kB] Err:1 http://security.debian.org/debian-security buster/updates InRelease At least one invalid signature was encountered. Err:2 http://deb.debian.org/debian buster InRelease At least one invalid signature was encountered.

N: See apt-secure(8) manpage for repository creation and user configuration details. ``` I can reproduce it locally by running the `apt-get update` command manually in a docker container based on `maven:3.6.3-jdk-8` => `docker run -it --rm maven:3.6.3-jdk-8 /bin/bash`. However, I don't know how to fix it; all threads online are rather old. Any debian/docker gurus here to help with this?
