Cannot initiate the connection to archive.ubuntu.com:80

[quiet-ranger]

I am behind a corporate firewall and I have already followed the instructions on this page:
https://github.com/docker/kitematic/wiki/Common-Proxy-Issues-&-Fixes

Thanks to that I am able to access the docker hub. However, "docker build" is failing at the point the container is instructed to install new software. Here is the relevant extract from the console:

Step 2 : RUN apt-get -y update && apt-get install -y fortunes

As per the logs archive.ubuntu.com:80 (2001:67c:1360:8c01::18), the ubuntu server is resolving to an IPV6 address and it seems it is not reachable. Can you pls check your configurations and confirm the ipv6 behavior ?
ping @sanimej

[quiet-ranger]

I would check if I knew exactly what to. Which files should I look into or what commands would help me here?

[HackToday]

I think you need check your

ping archive.ubuntu.com

and also what's your host ifconfig related configuration.

[vponcelo]

I have the same problem I explain in this post, and ping archive.ubuntu.com works but docker run ubuntu ping archive.ubuntu.com returns this:

ping: unknown host archive.ubuntu.com

From the post I linked, it seems is a problem of the host DNS when you don't specify explicitly non-local DNS such as those from Google, for example for security or institutional reasons. It should be solved if you update your host DNS with sudo vi /etc/resolvconf/resolv.conf.d/base
Then adding the DNS you want like those from Google with:

nameserver 8.8.8.8
nameserver 8.8.4.4

And finally update resolvconf with sudo resolvconf -u

However, you may not be allowed to do it for security reasons of your instition, like me. In this case I didn't reach a solution. Please, if you find an alternative way to solve this that could work for me share it here. Thank you.

[sanimej]

@vponcelo What are the nameservers listed in your hosts's /etc/resolv.conf ?

In the other linked issue you said you are able to ping 8.8.8.8 from your host. Can you try dig @8.8.8.8 archive.ubuntu.com from your host ? The problem could be that your org's security policy might allow DNS queries only to their internal DNS servers and block anything going to external servers.

Can you also send your docker info output ?

[vponcelo]

Thanks for your answer. @sanimej exactly, I also think this is the problem. The nameservers listed in my host are internal and I'm not allowed to put external ones like those from Google. I guess it should be an alternative solution to reach specific DNS as exceptions or something like that (but I have no clue how).

Best,

[vishal-yadav]

I also faced the same issue but only while building image from Dockerfile. I was able to apt install packages in interactive mode from container. Any suggestion?

Building image from Dockerfile:

Dockerfile:

MAINTAINER Vishal Yadav <vishal.yadav@zzz.com>

[thaJeztah]

@vishal-yadav each step in a Dockerfile is executed in a new container. When running RUN export foo=bar, that variable is only present during that step, but no longer there in the next step (container)

For docker build, you can use --build-arg, which sets environment variables in the container during build only, so they do not remain in the image after build. And there's no need to change your Dockerfile for http_proxy variables, as they are supported by default

For example

docker build --build-arg http_proxy=<proxy>:8080 .......

If the http_proxy environment variable is set on your host, you can even omit the =<proxy>:8080

[vishnu-kumar]

in Dockerfile i tried below and it worked.

RUN http_proxy='http://proxy:port/' https_proxy='http://proxy:port/' apt-get -y update && http_proxy=''http://proxy:port/' https_proxy=''http://proxy:port/' apt-get install -y fortunes

[thaJeztah]

There's no need to add it to your Dockerfile; *_proxy variables are supported as --build-arg by default, so this should work without modifying your Dockerfile;

docker build --build-arg http_proxy='http://proxy:port/' --build-arg https_proxy='http://proxy:port/' ..

[thaJeztah]

Note that this is being worked on as part of #30588, and #26318 (which are temporarily closed, but will be reopened after DockerCon)

[Pizzabakerz]

i think you should force the connection to ipv4
check out this it might help
https://support.purevpn.com/how-to-disable-ipv6-linuxubuntu

[avi6gupta]

In my case ,my institution was using ipv4 but Ubuntu was trying ipv6 also, so just changing the method from Automatic to Ignore in ipv6 settings worked.
