This looks very similar to an issue from last year: http://apache-ignite-users.70518.x6.nabble.com/Apache-Ignite-downloads-are-redirecting-from-https-to-http-td31428.html
When I attempt to run `apt-get update` on Ubuntu 18.04 with the Apache Ignite repository in /etc/apt/sources.list, the update fails due to an https to http redirect. Here's the output from stdout: WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
