Machine Learning - Lab 1 - login error

[mrauch]

Hello,
I got a problem logging in on localhost:9200 (step 7 in Lab 1) even I followed all instructions for installing elasticsearch and x-pack. This error occurs:
{"error":{"root_cause":[{"type":"security_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}}],"type":"security_exception","reason":"failed to authenticate user [elastic]","header":{"WWW-Authenticate":"Basic realm=\"security\" charset=\"UTF-8\""}},"status":401}
How can I solve this?
Cheers
Miriam

Hello,

The course was built using Elasticsearch 5.x. You may need to ensure you're using 5.6 or earlier.

We will update the labs to use Elasticsearch 6 soon. In the meantime, if you want to continue using v6.x of the Elastic Stack then read this to see how to install X-Pack. It's pretty simple, but a bit different from 5.x.
