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 Bugs, which is subscribed to 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1638842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
