build error: curl: (6) Could not resolve host: codeload.github.com

Hello,

I want to make small changes to your image by making some changes to your Dockerfile.

I started with your full code without changes to look or it would work.

command: docker build .

Log with error:

7 18.62 Executing ca-certificates-20211220-r0.trigger

Can someone please give me a hint what i am doing wrong?

Thanks in advance,

Nico

You have the same problem every time you try to build ?

The error indicate that codeload.github.com cannot be resolved. Can the name be resolved if you run nslookup codeload.github.com ?

Thanks for your quick reply.

You pointed me to the right direction.

nslookup codeload.github.com gave Server: Unknown. In fact it gave this error for every server. I tried it for 3 days without suc6. But just now it worked like a charme.

I will invistigate why this happened.

But this issue can be closed.

Today i got the same problem wit nslookup. Server unknown.

The solution that worked is to diable IP V6 on my network-adapter.

I do not like this solution but at the moment i do nothing with IP V6 so i can live with it.
