Docker requires 64-bit installation, regardless of the Fedora version. Also, the kernel version should be at least 3.10. Check the kernel version before going ahead with installation using the following command:

$ uname -r
4.4.7-300.fc23.x86_64
Switch to root user
[os@osboxes ~]# su -
Password:
[root@vkohli ~]#

Update the existing DNF package by using the following command:

$ sudo dnf update

> name=Docker Repository 
> baseurl=https://yum.dockerproject.org/repo/main/fedora/$releasever/ 
> enabled=1 
> gpgcheck=1
