Hi Manoj, Thanks for reporting this. How often are you able to reproduce? Could you please share what you were aiming to achieve when you encountered the bug? This will give us a clearer picture of the context in which the bug occurred. Also, could you please provide level=TRACE logs when reproducing please? See https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/main/contrib/fedora/rpm/NetworkManager.conf#L27 for hints about logging. Thanks Hello, The goal is to disable IPv6 on "lo" loopback interface. This is getting enabled by NetworkManager service even "sysctl.conf" settings are configured to disabled IPv6 on all interfaces on the system. # disable ipv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 Created attachment 1982133 [details]
