Steps to reproduce

  1. DietPi-Update to latest version
  2. Run docker container ls

Following error message appears

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Expected behaviour

  • It should be listing all my containers and docker should be running

Actual behaviour

  • Docker fails to start

Extra details

  • root@DietPi-LocalServices:~# systemctl status docker -l

Tried updating Docker using the following command;

apt update
apt install docker-ce containerd.io docker-ce-cli

And also tried to run: dietpi-software reinstall 134

Neither helped and docker does not work correctly.

Thanks for any and all help!

I guess you are hit by following bug of Docker software DietPi-Software | Docker: Service fails to start after upgrade (AppArmor) · Issue #6126 · MichaIng/DietPi · GitHub

Did not see that, thank you. I’ll give it a try!

Check this video if it helps you.

5

just to avoid a missunderstanding, this is NOT a DietPi issue. It’s a bug in Docker software directly.

Issue is describe on Docker release notes as known issue Docker Engine 23.0 release notes

6

Finally, Docker 23.0.2 has been released fixing the issue on x86 Docker Engine 23.0 release notes

7

Thank you for posting this. I’ll give the latest version a go tonight and see if its fixed it for me!

8

you can update docker by running apt update && apt upgrade

I’m afraid it hasn’t worked for me :frowning:

Any thoughts of what i can do?

Thank you!

Did you tried to reboot your system?

11

Yeah tried rebooting and made no difference.

12

Your issue seems to be completely different from the original one. Can you share system logs please

journalctl -u docker.service

Thank you for looking into this.

14

Looks like there is a typo inside your daemon.json

15

es if possible, share the content of /etc/docker/daemon.json

16 
{
    "data-root": "/mnt/dietpi_userdata/docker-data",
    "log-driver": "journald",
    "log-level": "warn",
    "debug": false
}
#{"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}

The Daemon.json is exactly the same as the working version of docker on my system.

I did try to remove the # but it then just complained about the open bracket { instead.

17

I think there should be only one { and } in the whole document.
Also # is not allowed. Comments can be written with //

{
“data-root”: “/mnt/dietpi_userdata/docker-data”,
“log-driver”: “journald”,
“log-level”: “warn”,
“debug”: false
//“hosts”: [“tcp://0.0.0.0:2375”, “unix:///var/run/docker.sock”]
}
18

I’ll give that a go and feedback shortly!

You still have not valid characters in your .json file
