Hi, Quick update regarding the system tests. My environment is back but now we're hitting https://issues.apache.org/jira/browse/KAFKA-19501.
Debian buster which is used in the system tests is out of support and it's apt repository has now been archived. It worked till last week but now it's gone so we get an error when building the Docker image. We had only updated trunk to use bullseye. I've just backported the fix to 4.1: https://github.com/apache/kafka/commit/d5a3acda897890379edb8819f15b144fcea564b0 The fix is only in tests/docker/Dockerfile and tests/docker/ducker-ak. My understanding is that these files are not part of any of the release artifacts. So I'm considering keeping the RC1 artifacts and running the system tests with the fix. Let me know if my understand is incorrect, or if you'd prefer building a new RC regardless. Obviously if we find issues with RC1, we'll do another RC anyway.
