Docker currently supports the following Ubuntu systems:

• Ubuntu xenial 16.04 (LTS)
• Ubuntu Wily 15.10
• Ubuntu trusty 14.04 (LTS)
• Ubuntu precise 12.04 (LTS)

Complex operations

• Check kernel version

  Docker requirements are 64-bit Ubuntu (whichever version). In addition, the kernel must be at a minimum of 3.10. 3.10 The latest version or newer version also line. The reason is that prior to 3.10, the version lacks the features required by Docker to run some containers. These old versions of bugs often lead to data loss.

  • Use uname -r to check the kernel version:

    [~] uname -r4.10.0-28-generic

• Check Device Mapper

  Is-l /sys/class/misc/device-mapper

• Update apt Source

  Docker's APT warehouse includes Docker 1.7.1 and later. To set APT to use the latest repository package, use sudo or root permissions to log on to the computer. Update the installation package information to ensure that APT uses the HTTPS protocol and that the CA certificate has been installed.

  • Update the installation package information to ensure that APT uses https the protocol and that the CA certificate has been installed.

     $ sudo apt-get update $ sudo apt-get install apt-transport-https ca-certificates

  • Add a new GPG key

    $ sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

  • Add or edit the Docker.list file in the source list to add entry (Ubuntu xenial 16.04 (LTS)) according to the system version

    vi /etc/apt/sources.list.d/docker.list

    Comment out the original content, add the following content:

    # deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial edgedeb https://apt.dockerproject.org/repo ubuntu-xenial main

  • Re-perform the update operation and remove the old repo

    $sudo apt-get purge lxc-docker  //没有安装的话，跳过
