Problems trying to fetch new containers

7ore · Jun 17th 2022

My docker containers are running but tab "Docker images repo" is empty and when I try to pull a new image I get.

Code

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; docker pull 'emby/embyserver:latest'' with exit code '1':

And when I check the logs I can see that dockerd have issues:

Code

Have there been a change in docker? I checked if there was a new plugin update, but found none.

Any ideas on how to proceed?

This is usually, a symptom of bad DNS resolution or running behind a proxy.

Check/change your DNS to 8.8.8.8 and see if it fixes it.

You can also try in CLI:

ping -c 5 google.com

ping -c 5 registry-1.docker.io

A simple google search would tell you this much:

Error getting v2 registry: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io - Search (bing.com)

Thanks. I normally use 1.1.1.1 as DNS and that usually is a stable dns.
Switched to Google dns and get the same issue (but Google work)

It might be as simple as registry-1.docker.io being down currently.
I tried from two remote servers I have with the same issue.

So I suspect I just have to wait it out...

Are you really on OMV4? If so consider updating to OMV6, which is the current version based on the current Debian version.

Thanks.

Yes it is probably about time to do that.

I am a bit hesitant as it usually goes sideways, giving me a lot of problems before it is up and running again.

But if I go to 6 now, that might give me peace for a couple of more years to come...
