### Client
show original
version 17.04.0-ce and 17.05.0-ce of Docker are out since more than a month and the official Ubuntu repository from docker still has the old version 17.03 as you can see here:
https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/
Any ideas when the Ubuntu packages will be available? or am I lookint at the wrong place maybe?
Cheers,
