Installing Ubuntu Server 24.04 LTS on a Windows 11 Pro computer using WSL2



In this post we install and configure an instance of Ubuntu Server
under WSL2 for Linux. Many developers are going to choose to use WSL2,
so we guide them to install the Ubuntu Server version of WSL2. This
provides a more standard environment referenced by many howto procedures
on the Internet.

WSL2 enables a computer running Windows 11 Pro to host a guest instance of Ubuntu Server:



WSL2 offers some advantages for a developer experience

WSL2 offers some advantages for a local developer in terms of
networking: if they install a service that opens a port, like port
22/tcp for SSH, that same port is opened on localhost of the Windows
machine hosting the WSL2 Ubuntu Server instance. A developer can SSH to
port 22 on localhost, without configuring a static IP address or port
forwarding. This eliminates the need to configure virtual switches,
static IP addresses, and port forwarding. In addition, WSL2 provides a
file mounts of the Windows file system within Linux, and a file mount of
the Linux filesystem within Windows.

Other ways to install Ubuntu Server on a Windows 11 Pro computer

There are other ways to install Ubuntu Server on a Windows 11 Pro
computer, including Windows Hyper-V. If you need to host multiple
instances of Ubuntu Server with static IP addresses and subnet routing,
consider using Hyper-V instead.
