netplan.io 0.40 in cosmic contains this fix. ** Description changed:
+ [Impact] + Users configuring IPv6 static address with NetworkManager as a backend. + + [Test cases] + 1) Configure netplan for static addresses for IPv6, dns settings, but no IPv4 configuration: + + [...] + ens8: + accept-ra: false + addresses: ['23:b0:87:58:65:f7:fb:8b/45', '63:94:73:e1:46:15:79:58/50'] + nameservers: + addresses: ['f2:9d:bc:04:7b:87:ec:28'] + search: [lab, home] + renderer: NetworkManager + + 2) Verify that no IPv4 configuration was added in NetworkManager: + + 'nmcli' + + 3) Verify that warnings aren't in /var/log/syslog about invalid + properties. + + + [Regression potential] + Possible regressions might include issues with setting DNS search domains or addresses for the nameservers. Any issues related to resolving addresses on such an IPv6 network, where the nameserver or search domains are incorrectly added. + + --- + In an IPv6 static setup with NetworkManager, such as the following: - ens8: - accept-ra: false - addresses: ['23:b0:87:58:65:f7:fb:8b/45', '63:94:73:e1:46:15:79:58/50'] - nameservers: - addresses: ['f2:9d:bc:04:7b:87:ec:28'] - search: [lab, home] - renderer: NetworkManager + ens8: + accept-ra: false + addresses: ['23:b0:87:58:65:f7:fb:8b/45', '63:94:73:e1:46:15:79:58/50'] + nameservers: + addresses: ['f2:9d:bc:04:7b:87:ec:28'] + search: [lab, home] + renderer: NetworkManager we see the following error in syslog: NetworkManager[19666]: <warn> [1532665946.1502] keyfile: error loading connection from file /run/NetworkManager/system-connections/net plan-ens8: invalid connection: ipv4.dns-search: this property is not allowed for 'method=link-local' netplan renders an ipv4 dns search property, even though there is no configured ipv4 address. NetworkManager doesn't like this and it prevents the connection from being configured. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786726 Title: dns-search rendered for ipv4 when no addresses configured To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1786726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
