I'm a very first user of Ubuntu. I failed to install Ubuntu in wmware ,so I installed Ubuntu application in Microsoft app store and everything was quite all right. But when I insert shutdown or halt command to power off my ubuntu I kept getting 'system has not been booted with system as init system (PID 1). Can't operate' error message.
I tried to using docker following with this link (https://blog.jayway.com/2017/04/19/running-docker-on-bash-on-windows/) but I failed after going to Number 2 process many times. I'm not sure my failure is because of installing docker toll box instead of normal one. (my computer is just windows 10. not a windows pro)
I think I have to try other thing. If you don't mind me asking, how can I slove this problem?
(and one more. If I just click 'X' button at the top of right side, is it different with shutting down Ubuntu using 'halt' or 'shutdown' command?
Thank you
I found this useful: https://linuxhandbook.com/system-has-not-been-booted-with-systemd/
In my case
# start docker using systemctl
sudo systemctl docker start
# returns:
#
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
The basic advice is:
# check if your system is using `systemd` or `sysvinit`
ps -p 1 -o comm=
If the command doesn't return systemd, and in my case, Ubuntu-20.04 on WSL, the command returned init, then use the command pattern
# start services using sysvinit
service docker start
This works for me.
