Arch not resolving mirrors.kernel.org

[TheNodi]

Arch container on Travis CI doesn't want to resolve mirrors.kernel.org: Job #113.4

I've tried to manually re-sync pacman database (c177f0a) before running any command, but it doen't work either ( Job #114.4 ).

I don't use Arch so I don't know if this is a Travis-related problem or a misconfiguration on the box. It's working on my local system using:

./run-tests arch '--privileged  --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro'

Did you tried pacman with the ' --debug' parameter or maybe disabling ipv6 could work?

[TheNodi]

It's a DNS problem, but I don't get the reason of it.
I'm gonna try to rebuild the container with dnsutils and see if I find more information.

IPv6 is disabled

$ ip addr

/etc/resolv.conf

Pings look fine for the dns servers:

But it doesn't resolve them anyway:

$ ping -c 4 mirrors.kernel.org

$ curl https://google.com

$ curl http://mirrors.kernel.org/
curl: (6) Could not resolve host: mirrors.kernel.org

Leo, should we disable the arch travis build in the meanwhile? I don't know why it doesn't work. I tried it locally and it worked perfectly.

[TheNodi]

I was thinking the same thing. It might be connect to the fact that the base image is the only one which doesn't come from the official docker repository.

I don't have the time to debug it so I'll leave this issue here for anyone who wants to help.

[cpriego]

It's already done, I did not disabled it but set it on the allowed failures section so that we can test it
