I'm trying to install Docker on a Ubuntu 64 machine following the official installation guide. Sadly Ubuntu seems it is not able to locate the docker-ce package. Any idea to fix it or at least to track what is happening ?Here some details for you...$ uname --all; sudo grep docker /etc/apt/sources.list; sudo apt-get install docker-ceLinux ubuntu 4.4.0-62-generic #83-Ubuntu SMP Wed Jan 18 14:10:15 UTC 2017 x86_64 x86_64 x86_64 GNU/Linuxdeb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable.# deb-src [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable.Reading package lists...
