I'm trying to add a github action workflow for ovirt-imageio. The yml file is simple: https://github.com/nirs/ovirt-imageio/commit/21da91274b7b4722167c2415d1c1... And all the jobs run, but tons of tests are failing: https://github.com/nirs/ovirt-imageio/actions/runs/1527728851 The typical failure is: 2021-12-01T20:50:07.6424921Z address = ('::', 43001), timeout = <object object at 0x7f2cb7d16270> 2021-12-01T20:50:07.6425749Z source_address = None 2021-12-01T20:50:07.6425985Z 2021-12-01T20:50:07.6426421Z def create_connection(address, timeout=_GLOBAL_DEFAULT_TIMEOUT, 2021-12-01T20:50:07.6426954Z source_address=None): ... 2021-12-01T20:50:07.6435579Z host, port = address 2021-12-01T20:50:07.6435942Z err = None 2021-12-01T20:50:07.6436563Z for res in getaddrinfo(host, port, 0, SOCK_STREAM): 2021-12-01T20:50:07.6437402Z af, socktype, proto, canonname, sa = res 2021-12-01T20:50:07.6437834Z sock = None 2021-12-01T20:50:07.6438146Z try: 2021-12-01T20:50:07.6438522Z sock = socket(af, socktype, proto) 2021-12-01T20:50:07.6439032Z if timeout is not _GLOBAL_DEFAULT_TIMEOUT: 2021-12-01T20:50:07.6439538Z sock.settimeout(timeout) 2021-12-01T20:50:07.6440109Z if source_address: 2021-12-01T20:50:07.6440522Z sock.bind(source_address) 2021-12-01T20:50:07.6440916Z > sock.connect(sa) 2021-12-01T20:50:07.6441573Z E OSError: [Errno 99] Cannot assign requested address I guess that ipv6 is disabled, and google confirms that github actions and ipv6 is an issue. In travis we enabled ipv6 in docker using this script: https://github.com/oVirt/ovirt-imageio/blob/master/travis/configure-docke... Run before starting the job: https://github.com/oVirt/ovirt-imageio/blob/61f023bf1e45da4e9859327845103... I did not try to run this script yet, since I'm not sure we have a way to run stuff *before* the container runs in github actions. I hope someone has some insight on a way to solve this. Nir
