Public bug reported: To replicate:
Connect to a wifi network (wired untested). The problem occurs most consistently for DHCP configured connections but is also a significant problem for manually configured connection. Expected results: IPv4 and IPv6 should both auto-configure correctly and be usable: as they were in previous versions of Ubuntu, and still are on other devices and operating systems. Actual results: IPv6 is automatically configured correctly and I have no difficulty using IPv6 services. Most of the time no IPv4 address is configured. Manually configuring an IPv4 address is possible but usually does not result in a working IPv4 connection (pinging the gateway gives "destination host unreachable") ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: network-manager 1.10.6-2ubuntu1 ProcVersionSignature: Ubuntu 4.15.0-22.24-generic 4.15.17 Uname: Linux 4.15.0-22-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.1 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Thu Jun 7 20:05:56 2018 EcryptfsInUse: Yes IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2018-05-11 (26 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) IpRoute: default via 192.168.178.1 dev wlp2s0 proto static metric 600 169.254.0.0/16 dev wlp2s0 scope link metric 1000 192.168.178.0/24 dev wlp2s0 proto kernel scope link src 192.168.178.28 metric 600 NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=false SourcePackage: network-manager UpgradeStatus: No upgrade log present (probably fresh install) nmcli-dev: DEVICE TYPE STATE DBUS-PATH CONNECTION CON-UUID CON-PATH wlp2s0 wifi connected /org/freedesktop/NetworkManager/Devices/3 2degrees Broadband - D377 10b8508a-4b0a-4ec4-9adb-e30685236fb7 /org/freedesktop/NetworkManager/ActiveConnection/6 B8:C1:11:CA:B7:3A bt disconnected /org/freedesktop/NetworkManager/Devices/4 -- -- -- enp1s0 ethernet unavailable /org/freedesktop/NetworkManager/Devices/2 -- -- -- lo loopback unmanaged /org/freedesktop/NetworkManager/Devices/1 -- -- -- nmcli-nm: RUNNING VERSION STATE STARTUP CONNECTIVITY NETWORKING WIFI-HW WIFI WWAN-HW WWAN running 1.10.6 connected started full enabled enabled enabled enabled disabled ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug bionic -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1775540 Title: Intermittent ipv4 connectivity on bionic beaver Status in network-manager package in Ubuntu: New Bug description: To replicate: Connect to a wifi network (wired untested).
