System has not been booted with systemd as init system (PID 1)

I have Ubuntu 20.4 in Windows ( WSL2 ), when in reloading any service I'm getting below error

Error: 

failed to connect to bus: host is down

failed to connect to bus: host is down wsl2

System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

Solution :

1 – Update the system

sudo apt-get update

2 – Install below package

sudo apt-get install -yqq daemonize dbus-user-session fontconfig

3 – execute below command to fix the issue

sudo daemonize /usr/bin/unshare --fork --pid --mount-proc /lib/systemd/systemd --system-unit=basic.target

exec sudo nsenter -t $(pidof systemd) -a su - $LOGNAME

4 – check the version

snap version

Enjoy!

Now we can restarted the system service without error,

Thanks you !!
