As configured on install (at least in 24.8.4 I installed), the netplan config files try to manage all networking interfaces - which breaks the virtual bridge interfaces that containers and VM managers like Podman, Docket, etc create and use. See https://github.com/moby/moby/issues/40217#issuecomment-2041628162 for more information If networkctl shows podman* or veth* as managed then this is probably the problem breaking your container networking. To work around this issue, I modified the file /etc/netplan/10-dhcp-all-interfaces.yaml to only manage en* interfaces rather than all interfaces, followed by netplan apply. # Added by Armbian # # Reference: https://netplan.readthedocs.io/en/stable/netplan-yaml/ # # Let systemd-networkd manage all Ethernet devices on this system, but be configured by Netplan. network: version: 2 renderer: networkd ethernets: all-eth-interfaces: match: name: "en*" dhcp4: yes dhcp6: yes ipv6-privacy: yes # Enabled by default on most current systems, but networkd currently doesn't enable IPv6 privacy by default, see https://man.archlinux.org/man/systemd.network.5 lo-interface: match: name: lo dhcp4: yes dhcp6: yes ipv6-privacy: yes # Enabled by default on most current systems, but networkd currently doesn't enable IPv6 privacy by default, see https://man.archlinux.org/man/systemd.network.5 Note: netplan doesn't support globs/etc on name line yet hence the need for two ethernets entries, see https://github.com/canonical/netplan/pull/202
