Enable systemd in WSL 2

NOTE: If you have Windows 11 there is now an official way to do this in WSL 2, use it if possible - see MS post here (WINDOWS 11 ONLY)

This guide will enable systemd to run as normal under WSL 2. This will enable services like microk8s, docker and many more to just work during a WSL session. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2.

• To enable systemd under WSL we require a tool called systemd-genie

• Copy the contents of install-sg.sh to a new file /tmp/install-sg.sh:

# On disk local Quartz JobStore using H2; add 'com.h2database:h2:1.4.197' to your dependencies
org.quartz.scheduler.instanceName = MyScheduler
org.quartz.threadPool.threadCount = 3

# generic jdbc job store
org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTX
org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
org.quartz.jobStore.dataSource = disk

# persist to H2 database at path '/tmp/MyScheduler.quartz.h2'

WSL 2 XServer Setup

This guide will setup WSL 2 to be able to connect to an XServer installed on your host Windows machine. Note: this was tested on Windows 10 Build 2004, running Ubuntu 20.04 LTS in WSL 2. The XServer software used was VcXsrv; remember to disable authentication for this to work correctly.

• Open a WSL terminal

• Fix an issue with dbus:

sudo sh -c "dbus-uuidgen > /etc/machine-id"
