EC2 AMI 2.4 / 2.5 dsc20 / dsc21 dependency problem

Question

I am trying to create a 1 node cluster of Datastax community publications using this recommendation on EC2 m3.xlarge (eu-west), Here are the options provided:

  --clustername cassandra
  --totalnodes 1
  --version community

As mentioned in the manual, I opened these ports:

  22
  8888
  1024-65355

Here is the error I found in ~ / datastax_ami / ami.log:

         The following packages have unmet dependencies:
