And what is the output of echo $? right after running that command? The not found part makes me think it is returning a non-zero return code which prevents docker from being installed. But it also might prevent dockers from being downloaded because something in your networking/dns is doing something wrong.

This is what it should look like:

aaron@omv5dev:~$ /usr/bin/host hub.docker.com

hub.docker.com is an alias for elb-default.us-east-1.aws.dckr.io.

elb-default.us-east-1.aws.dckr.io is an alias for us-east-1-elbdefau-1nlhaqqbnj2z8-140214243.us-east-1.elb.amazonaws.com.

us-east-1-elbdefau-1nlhaqqbnj2z8-140214243.us-east-1.elb.amazonaws.com has address 3.221.200.233

us-east-1-elbdefau-1nlhaqqbnj2z8-140214243.us-east-1.elb.amazonaws.com has address 3.212.25.17

us-east-1-elbdefau-1nlhaqqbnj2z8-140214243.us-east-1.elb.amazonaws.com has address 54.164.28.179

i tried using dhcp and manual configuration:

- dhcp give me the address of the router to be DNS server

- manual i put both the classic 8.8.8.8 and 8.8.4.4 for DNS addresses, or the router address

but, nothing changes.

here the entire code

UPDATE

i've updated the whole system, tried many times to install from omv-extras GUI but the problem remains.

The system is able to correctly ping websites, so the connection seem to work well.

I can't find information about interaction between the scripts of the GUI or an eventually manual installation of docker, or just how to manually install a compatibile version with OMV.

Sorry, i'm a beginner in this beautiful system... i'm reading a lot trying to fix this problems, but without success.

it's possible that a LOCALE configuration problem can generate this DNS problem?

more info is needed.

eg: what version of OMV do you have?, what CPU do you use (AMD64 or Arch) ?, etc....

and please post the exact message that is show when you try to instal dockerGUI

Thanks for the fast replay

OMV 5.4.0-1 Usul , installed on a 32gb usb key inside a Hp Proliant Microserver gen8 (2gb ram, intel celeron g1610t)

This is the response when i try to install Docker from the omv-extras menu Gui

Docker storage :: /var/lib/docker
Agent port:: 8000
Web port:: 9000
Opt-out :: 1
arch   :: amd64
option :: docker
state  :: install
extras :: 5.3
DNS error.  Exiting ...
Done.

Eccomi, anch'io italiano

Hi,

i've the same exact problem...

but the DNS is working correctly because the system is able, for example, to ping google.com ... so i'm not able to fix this.

in my case, the installation is on a usb key (with flash plugin)

There are an other way to fix this problem?

i'm reading about manual installation, but it's clear that usually doing this i will mess up the system... since i'm a beginnner
