I manually tested the Windows/ARM64 installer from this PR against Ubuntu 26.04 WSL2 instance and it worked fine for docker-ce install.

[tyler36]

Confirmed working on Win10 WSL2 (Ubuntu 26.04) with Docker Desktop.
Good stuff!

Test

1. Download ddev-windows-amd64-installer.zip
2. Install with following
   • Current User
   • WSL2 with Docker Desktop or Rancher
3. Follow quickstart for Laravel (composer version)
4. Confirm Welcome page displays in browser (ddev launch)

@rfay, @tyler36, where did you get Ubuntu 26.04 WSL?

Did you install WSL image from here https://releases.ubuntu.com/26.04/ or manually upgraded 24.04 to 26.04?

> wsl --install Ubuntu-26.04
Invalid distribution name: 'Ubuntu-26.04'.
To get a list of valid distributions, use 'wsl.exe --list --online'.
Error code: Wsl/InstallDistro/WSL_E_DISTRO_NOT_FOUND

> wsl --list --online
The following is a list of valid distributions that can be installed.
Install using 'wsl.exe --install <Distro>'.

@stasadev

Ubuntu 26.04 is available from Ubuntu at Get Ubuntu on WSL.

[tyler36]

I saw #8350 last weekend which nudged me to try it.

[stasadev]

I confirm that it works for me too.

[rfay]

I got Ubuntu 26.04 (ARM64) image from https://cdimage.ubuntu.com/releases/26.04/release/ (https://cdimage.ubuntu.com/releases/26.04/release/ubuntu-26.04-wsl-arm64.wsl) and installed it with wsl --import

[rfay]

The most important question for this PR is not whether it works on Ubuntu 26.04 (confirmed, thanks) but whether it works for Ubuntu 24.04, which most people will be using for some time. That's tested in the automated testing though, and I think it's great.

[stasadev]

I have Ubuntu-26.04 and Ubuntu-24.04 prepared, works fine with both.
