The command "docker run hello-world" does not output anything

cd flag

sudo apt-key list Docker

Uninstall docker

# sudo apt-get remove docker docker-engine docker.io containerd runc
sudo apt-get remove docker docker.io containerd runc

Comment out docker repository

sudo gedit /etc/apt/sources.list.d/docker.list

sudo more /etc/apt/sources.list.d/docker.list
# deb [arch=amd64 signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu   focal stable

I don't know if this is helpful, but I tried the command

ohn@cd0254nb032364:~$ docker pull busybox

And, that command does not seem to pull the image. If I list the images, there are none on the system, including hello-world.

john@cd0254nb032364:~$ docker images
REPOSITORY   TAG       IMAGE ID   CREATED   SIZE
john@cd0254nb032364:~$

So, maybe the issue is my internet connection, I'm unable to pull the images down. Is there a way to check this? Can the images be pulled manually?

How can I debug, or correct the setup so the docker command hello-world runs?

What do the log files say? (Probably syslog?)

Well, the download for the image wasn't complete, so `ctrl+c` will have killed the process. Have you tried rerunning again? And then waiting a while for it to complete extraction/download? If you don't do that it will never run.

I've reran it, and waited, but don't see any output. $ docker run --log-driver "syslog" hello-world Unable to find image 'hello-world:latest' locally latest: Pulling from library/hello-world 2db29710123e: Extracting 2.479kB/2.479kB

I don't see anything in syslog related to this. I just reran it after 13:10 and the last entry in syslog (unrelated) is at 13:08. Do I need to add a flag to turn on log saving?

Please provide the last 30 lines from `/var/log/syslog` after running the command, and also output of `docker ps -a`.

How did you install Docker - you seem to be missing some vital components.

When you update, please confirm Docker installation with output of: `docker version`

I've added remove / install, listed syslog, and listed docker ps -a. I think the information to solve the problem is in the syslog display, but I'm not familiar with the output.

I think you're right that somehow the problems comes from the fact that you're not able to pull the images. Are you behind a firewall that blocks anything? Do you have enough disk space? Maybe you should rephrase your entire question to focus on that you can't pull Docker images.

You seem to be missing some vital components. Notice this:

 Runtimes: io.containerd.runtime.v1.linux runc io.containerd.runc.v2
 Default Runtime: runc
 Init Binary: docker-init
 containerd version: 
 runc version: 
 init version:

On a working system, this should read: (the version numbers are from my Ubuntu 22.04 with Docker 20.10.21 installed from the Docker repos)

 Runtimes: io.containerd.runc.v2 io.containerd.runtime.v1.linux runc
 Default Runtime: runc
 Init Binary: docker-init
 containerd version: 1c90a442489720eec95342e1789ee8a5e1b9536f
 runc version: v1.1.4-0-g5fd4c4d
 init version: de40ad0

If you installed Docker from the Ubuntu repos, run: (I don't think many people use this option, but still..)

sudo apt install --reinstall docker.io

If you installed Docker from the Docker repos, run:

sudo apt install --reinstall docker-ce docker-ce-cli containerd.io docker-compose-plugin

Also, remember to add your user to the docker group.

Thank you for the response. I'll update the original question, but I still get the same error.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
