Description of problem: I am trying to use podman under CentOS 7 to run a Fedora 35 container. Version-Release number of selected component (if applicable): podman-1.6.4-29.el7_9.x86_64 from CentOS Extras How reproducible: Always Steps to Reproduce: 1. podman run -it --rm registry.fedoraproject.org/fedora:35 yum check-update Actual results: Fedora 35 - x86_64 0.0 B/s | 0 B 00:00 Errors during downloading metadata for repository 'fedora': - Curl error (6): Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=fedora-35&arch=x86_64 [getaddrinfo() thread failed to start] Error: Failed to download metadata for repo 'fedora': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=fedora-35&arch=x86_64 [getaddrinfo() thread failed to start] Expected results: A list of packages needing updating. Additional info: Works with Fedora 34. It seems that some change in F35 broke host name lookup. Seems similar to <https://bugzilla.redhat.com/show_bug.cgi?id=2007758>, but that uses systemd-nspawn instead of podman. Fetching a web page by IP address (`curl http://192.168.1.10/`) works. Works on a Fedora 34 host.
I see this too, name resolution on Debian here not working for newer Fedora containers. Fedora35 hypervisor: all of Fedora34/35/36 containers work Debian Bullseye hypervisor: Fedora34 works, Fedora35/36 do not work Output on Bullseye: # podman run -it registry.fedoraproject.org/fedora:34 bash -c 'curl fluxcoil.net' <html> <head><title>301 Moved Permanently</title></head> <body> <center><h1>301 Moved Permanently</h1></center> <hr><center>nginx/1.18.0</center> </body> </html> # podman run -it registry.fedoraproject.org/fedora:35 bash -c 'curl fluxcoil.net' curl: (6) getaddrinfo() thread failed to start # podman run -it registry.fedoraproject.org/fedora:36 bash -c 'curl fluxcoil.net' curl: (6) getaddrinfo() thread failed to start
