Comment on How do I stop Docker trying to pull from IPv6?

Even if it has an IPv6 address that can’t route, it’s odd that the OS isn’t falling back to IPv4.

But disabling IPv6 in the OS should fix it, as this is not a docker problem.

But disabling IPv6 in the OS should fix it

I’ve already followed the instructions I could find to do that, but it didn’t work. Either disabling IPv6 isn’t the solution, or the instructions for how to disable it are incomplete. (You can see comments elsewhere in the thread for more detail.)

Can you give us the full output of the following commands?

ip addr

sysctl net.ipv6.conf.all.disable_ipv6
