*** This bug is a duplicate of bug 1676547 *** https://bugs.launchpad.net/bugs/1676547
I'm adding an observation here because the NetworkManager work-around thread is here and not in #1676547. Confirmed with additional information: Ubuntu 20.04 workstation ISO (downloaded August 2020) exhibits the issue when run in the LiveCD "Trial" mode. The Gnome "Settings" UI does not by default show the "Wired" menu by default even if the underlying NIC is not servicing DHCP. The network icon is also missing from the top status bar. This behavior differs from Ubuntu 16.04 & 18.04 LiveCD ISO images. In my test cases, copying /usr/lib/NetworkManager/conf.d/10-globally- managed-devices.conf to /etc/NetworkManager/conf.d and then setting "unmanaged-devices=all" followed by restarting NetworkManager causes the menu to appear. It is worth pointing out that once installed the menu appears as expected once rebooted, so this issue is specific to the LiveCD instance and not the installed instance. I'm not going to try to guess why the developers decided to hide this functionality in the LiveCD, but I for one am disappointed because I am working in a mixed DHCP/VLAN network environment where static IP addresses are the rule rather than the exception. -- 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/1638842 Title: network-manager does not manage ethernet and bluetooth interfaces when Ubuntu 16.10 is installed using chroot/netboot method Status in network-manager package in Ubuntu: Won't Fix Bug description: Hello, I installed Ubuntu 16.10 using a chroot. I use network-manager to manage connections. My system is up-to-date (so I use network-manager 1.2.4-0ubuntu1). Wifi works perfectly but I cannot connect to wired networks and using my phone's Bluetooth connection. Corresponding devices are said to be unmanaged by network-manager. nmcli dev outputs: DEVICE TYPE STATE CONNECTION enp1s0 ethernet unmanaged -- wlp2s0 wifi disconnected -- 6C:9B:02:2C:EE:2C bt unmanaged -- hfp/org/bluez/hci0/dev_6C_9B_02_2C_EE_2C gsm unmanaged -- lo loopback unmanaged -- The following command has no effect: sudo nmcli dev set enp1s0 managed yes I can connect to a wired connection by doing: ifconfig enp1s0 up dhclient enp1s0 There is nothing in the file /etc/network/interfaces. Everything works perfectly if I downgrade network-manager to this version: network-manager_1.2.2-0ubuntu0.16.04.3_amd64.deb (http://packages.ubuntu.com/xenial-updates/amd64/network- manager/download). I had to install libreadline6 and downgrade nplan to meet dependencies. I don't know what to join to this bug report so please ask in case anything is needed.
