What are the system requirements for Ubuntu Server?

Ubuntu is one of the top free operating systems. The number of PCs, servers and virtual machines that have booted Ubuntu runs into the hundreds of millions.

And although the operating system and server software are free, that doesn't mean they aren't powerful. The incredible CGI effects of the smash-hit movie Avatar were all generated using an Ubuntu-powered server farm.

It may seem like a no-brainer to want to access this free, powerful software to run your own server. But you will need to make sure that your hardware is up to spec first.

Read on to learn more about the minimum Ubuntu server requirements you will need to get your server running smoothly.

Processor Speed

For a standard installation, it is recommended that you have a processor that runs to at least 1GHz.

This is the very minimum that they believe the Ubuntu server can run at. In our opinion, the best performance requires at least 2GHz. This is especially true if you are planning to run more resource-intensive applications.

If your hardware does not meet this specification, there is the option of doing a minimal install of Ubuntu. This requires a minimum of 300MHz to run.

However, the minimal install is a very stripped down version. It doesn't include many of the features that you might need or want, particularly if you are new to the system.


The official minimum spec to run the standard installation is 512MB (Debian installer) or 1GB (Live Server installer). Note that you can only use the Live Server installer on AMD64 systems.

Once again, these are the bare minimum specifications. Our recommendation is that you have at least 2GB of RAM, regardless of your installation method. This gives you some headroom to run the more RAM-hungry applications.

The minimal install is supposed to be able to run on only 384MB of RAM--but we don't recommend using so little.

Disk Space

In terms of disk space, we recommend 1.5GB for the base installation. If you're looking to install all the bells and whistles, then you'll need 2.5GB of disk space.

Realistically, you're going to have much more disk space than this. So to be honest, this isn't too much of an issue. It's more of a heads-up as to how much space the install will take up on your drive.

Interestingly, the minimal installation requires at least 1.5GB of disk space for the base system and 2.5GB for the full installation.

Other Requirements

You will also need a graphics card and a monitor capable of displaying at least 640x480 resolution. You'll also need a CD drive, USB port or internet connection for the installation itself.

Note that Ubuntu Server Edition only supports AMD64, ARM, POWER8, LinuxONE and z Systems.
