when installed docker.io , /etc/init.d/docker not found, so service can't start

[Pigo Chu]

I executed the following command

sudo apt install docker.io
sudo service docker start

than show message
docker: unrecognized service

I check /etc/init.d/docker , no file.

I also try other app.

sudo apt remove openssh-server
rm /etc/init.d/ssh
sudo apt install openssh-server

the /etc/init.d/ssh also not found

Win10: build 19624
ubuntu 20.04 WSL2 mode.

Sorry , ubuntu version is 20.04

[Patrick Wu (callmepk)]

Could you also post your Windows 10 version? Also, what version of WSL are you using? Just for your information, WSL1 do not support Docker at all.

Win10: build 19624
I run ubuntu in WSL2 mode.

I can confirm this bug. For now, it would be a good idea to use the Windows Docker Desktop with WSL2 backend to use both on Windows and WSL2: https://docs.docker.com/docker-for-windows/wsl-tech-preview/

[Pigo Chu (pigochu)]

Thanks Patrick Wu . I am still playing docker on wsl2 , I can copy docker init script from other machine and it works fine.

[Paolo Mainardi (paolomainardi)]

Same bug on Ubuntu 18.04 on Win10 + wsl2, it is basically impossible now to run docker on ubuntu distro on wsl2. To me, it's more than "Medium".

[Pigo Chu (pigochu)]

Paolo Mainardi

officile docker-ce can be installed , now has 20.04 version. so I remove docker.io and install it.

https://docs.docker.com/engine/install/ubuntu/ <= document show lastest is 18.0.4

[ALIAKSEI VENSKI (spellbound6666)]

The same issue for me...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Bryce Harrington (bryce)]

systemd is used in Ubuntu 20.04 for managing services. Some things still work with the legacy init system but in general you should be using commands like:

$ sudo apt install docker.io
$ sudo systemctl start docker
$ sudo systemctl status docker

Let us know if that does not work.

[Pigo Chu (pigochu)]

Hi bryce ~

This bug happend on WSL2.
So I use servce docker start/stop ...
No systemd and can't use systemd

Same here on WSL2 with Ubuntu 20.04. After
`$ sudo apt install docker.io`
I can't run docker service, but `docker-ce` from this manual
https://docs.docker.com/engine/install/ubuntu/
works fine.

Installing this way works for me as well on wsl: https://docs.docker.com/engine/install/ubuntu/
