Description Mark Wielaard 2022-05-05 21:59:36 UTC 
On a system that has ipv6 disabled debuginfod doesn't start up anymore because libhttpd MHD_USE_DUAL_STACK only works if it can open an ipv6 socket.

    debuginfod: Try without MHD_USE_DUAL_STACK if MHD_start_daemon fails
    
    On a systems that have ipv6 disabled debuginfod doesn't start up
    anymore because libhttpd MHD_USE_DUAL_STACK only works if it can
    open an ipv6 socket. If MHD_start_daemon with MHD_USE_DUAL_STACK
    fails try again without that flag set.
