Error while installing docker?

Question

ubuntu

I'm trying to install docker according to this instruction on ubuntu 18. There's really an instruction for 16, but it should probably work for newer ones too. I don’t know if this is important - I installed Ubuntu from the windows store via WSL. On the second team:

sudo apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D

An error is thrown:

Executing: /tmp/apt-key-gpghome.7n9oBmS6lL/gpg.1.sh --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys 58118E89F3A912897C070ADBF76221572C52609D
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.7n9oBmS6lL/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr

And apparently this dirmngr costs:

sudo apt-get install dirmngr

dirmngr is already the newest version (2.2.4-1ubuntu1).
The following package was automatically installed and is no longer required:
  libfreetype6
Use 'sudo apt autoremove' to remove it.

How to be?

Why don't you install the docker itself according to the manual?
https://docs.docker.com/install/linux/docker-ce/ub...
And there seems to be no support for ubuntu 18.04 in the docker reps yet.
You will need to install it from the artful turnip. To do this, add a file to /etc/apt/sources.list.d/docker.list :
and then further according to the instructions.
