As I use multiple Windows machines, all running the identical setup of WSL (Ubunto) I wanted to keep all these instances automatically updated.

I am using Ansible scripts to set up the WSL. While all the files are hosted on the file system (\mtn\c\…) I can throw away a WSL instance and create a new one within minutes.

While many packages are not available on Ubunto 18.04 LTS, I created a small Ansible task upgrading my WSL to the latest Ubuntu version available.

1. Start your WSL instance the very first time and run sudo apt-get update
2. Install ansible by running sudo apt-get install ansible
3. Make sure the Ansible scripts are located on the host system (e.g. c:\dev\…)
4. Start your WSL instance and change e.g. to /mnt/c/dev
5. Run your Ansible playbook as sudo

You can check your dist version with lsb_release -a:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 19.04
Release:        19.04
Codename:       disco

The Ansible tasks can be found here.
