If you're worried your documents might at some point be used by the likes of Google, Apple, or Microsoft to train their artificial intelligence (AI) models, know that you are not alone. In fact, some people have considered migrating to another cloud provider to deal with this worry. 

If you've grown concerned about the privacy of your content, there's an alternative that's free and brings the power of the cloud to your home network. That option is called Nextcloud and it's a powerful solution that can be used in place of Google Drive, iCloud, or OneCloud. And the best news is that you can deploy this cloud service such that it is only accessible from your home network.

To successfully install Nextcloud, you will need an instance of Ubuntu Server -- which is a Linux server -- up and running on your home network. For those who haven't heard of Linux, it's a free operating system you can install on computers (or as virtual machines) that is more powerful, flexible, reliable, and secure than either Windows or MacOS. 

You might either not know about Linux or believe it to be too challenging for your skills. But installing and running Linux involves much less effort than you might think. And as I recently wrote in an opinion piece, there's some important reasons why you should be using Linux at home.

In the end, the use of Linux at home is all about keeping your data safe from third-party services and having the ability to expand the applications, services, and tools available to you -- without having to break the bank or get a degree in computer science.

What's more, Linux is everywhere. Not only does it run on computers, but also on IoT devices, smart devices, appliances, automobiles, and more.

In this series on making use of Linux at home, I now want to show you how to install the Nextcloud on-premises cloud host. Think of it as your own Google Workspace, complete with documents, storage, calendar, email, and more.

It should come as no surprise given the title of this piece that there's a very easy way to install this cloud platform -- and I'm going to show you how it's done.

How to install a cloud service at home: It's easy

What you'll need: As mentioned above, you'll need an instance of Ubuntu Server up and running on your home network to successfully install Nextcloud. Fear not, as I've already explained how you can install this system in under 30 minutes. With that server running, you'll need a user with sudo privileges (which you create during the operating system installation).

That's it. Let's do this.

1. Log in to Ubuntu Server

The first thing is to log in to your Ubuntu Server instance, which will land you at the terminal window.

2. Install Nextcloud with snap

To install Nextcloud, issue the command:

sudo snap install nextcloud

3. Find the IP address of your server

The Nextcloud command line installation should go off without a hitch and finish in less than a minute.

When that finishes, you'll need to first know the IP address of your server with the command:

ip a

4. Access the web installer

Open a web browser and point it to http://SERVER (where SERVER is the IP address of your Ubuntu server).

5. Create an admin user

In the resulting window of your web browser, type a new username and password to be used as an admin user.

6. Install recommended apps

In the resulting window, click Install Recommended Apps to add the Calendar, Contacts, Mail, Nextcloud Office, and Talk apps (you can add more later). This installation will take a bit more time (less than five minutes).

Allow the installation to complete and you'll be presented with the Nextcloud Hub, where you can access all of the pre-installed apps and start using your in-house cloud service.

Next steps with Nextcloud

After the installation is complete, you can start using Nextcloud. 

However, I would suggest you at least configure the email server settings, so you'll be able to share and collaborate on files. To configure the email server, you'll first need to have an SMTP server. You can always use the Google SMTP server; the settings you'll need are:

• SMTP server: smtp.gmail.com
• Port: 465
• From email address: Your Gmail address
• Password: Your Gmail password (or app password, if you use two-factor Authentication with Gmail)

To configure the SMTP server, click your Nextcloud profile icon at the top right of the window and, from the dropdown, click Administration Settings. From the left sidebar, click Basic Settings, and then in the resulting window, scroll down until you see the Email Server section. Fill in the options as outlined above and click Save. With that process complete, click Send Email to make sure everything is working.

Once you've taken care of the SMTP server settings, click the Mail icon at the top of the window. When prompted, fill out the necessary information for your email account, and click Connect.

With this stage complete, your Nextcloud instance can do just about anything your other cloud services can offer
