## Prerequisites
Docker Engine - Community users should go to
[Get Docker Engine - Community for Ubuntu](/install/linux/docker-ce/ubuntu.md)
**instead of this topic**.
Confirm that all prerequisites are met before installing Docker Engine - Enterprise on Ubuntu.
To install Docker Engine - Enterprise, you need to know the Docker Engine -
Enterprise repository URL associated with your trial or subscription. These
instructions work for Docker on Ubuntu and for Docker on Linux, which includes
access to Docker Engine - Enterprise for all Linux distributions. To get this
information, do the following:
The product URL associated with your trial or subscription is required to install Docker Engine - Enterprise, which can be attained using the following procedure (note that these instructions apply to Docker on Ubuntu and for Docker on Linux, which includes access to Docker Engine - Enterprise for all Linux distributions):
- Go to [https://hub.docker.com/my-content](https://hub.docker.com/my-content).
- Each subscription or trial you have access to is listed. Click the **Setup**
1. Go to [https://hub.docker.com/my-content](https://hub.docker.com/my-content).
2. Each subscription or trial you have access to is listed. Click the **Setup**

- Copy the URL from the field labeled
3. Copy the URL from the field labeled
**Copy and paste this URL to download your Edition**.
Use this URL when you see the placeholder text `<DOCKER-EE-URL>`.

### Uninstall old versions
Older versions of Docker were called `docker` or `docker-engine`. In addition,
if you are upgrading from Docker Engine - Community to Docker Engine -
Enterprise, remove the Docker Engine - Community package.
Use the `apt-get remove` command to uninstall older versions of Docker Engine - Enterprise (called `docker` or `docker-engine`). In addition,
if you are upgrading from Docker Engine - Community to Docker Engine - Enterprise, remove the Docker Engine - Community package.
```bash
$ sudo apt-get remove docker docker-engine docker-ce docker-ce-cli docker.io
```
It's OK if `apt-get` reports that none of these packages are installed.
The `apt-get` command may report that none of the packages are installed.
The contents of `/var/lib/docker/`, including images, containers, volumes, and
networks, are preserved. The Docker Engine - Enterprise package is now called

need to use `aufs` instead, you need to configure it manually.

## Install Docker Engine - Enterprise
You can install Docker Engine - Enterprise in different ways, depending on your
needs.
- Most users
[set up Docker's repositories](#install-using-the-repository) and install
from them, for ease of installation and upgrade tasks. This is the
recommended approach.
- Some users download the DEB package and install it manually and manage
upgrades completely manually. This is useful in situations such as installing
Docker on air-gapped systems with no access to the internet.
Docker Engine - Enterprise can be installed either via [Docker repositories](#install-using-the-repository), or by downloading and installing the DEB package and thereafter manually managing all upgrades. The Docker repository method is recommended, for the ease it lends in terms of both installation and upgrade tasks. The more manual DEB package approach, however, is useful in certain situations, such as installing Docker on air-gapped system that have no access to the Internet.
### Install using the repository
Before you install Docker Engine - Enterprise for the first time on a new host
machine, you need to set up the Docker repository. Afterward, you can install
and update Docker Engine - Enterprise from the repository.
Naturally, to install Docker Engine - Enterprise on a new host machine using the Docker repository you must first set the repository up on the machine.
