Another note: in addition to VLANs, NetworkManager lists other interface types for which the dependencies aren't installed as well:
Bond Bridge Team The "ifenslave" and "bridge-utils" package would be needed for bonds and bridges to work out of the box. (I think bridge-utils might already be present on Xenial server since LXD requires bridges, but I'm not sure about desktop.) The "Team" option seems to be a Red Hat technology (in 'universe' in Ubuntu) which should probably be hidden from the menu unless the dependency is installed (separate issue). In summary, I think that not having these packages installed by default is a usability problem for both Ubuntu Server and Ubuntu Desktop. IMHO, we should ensure the following packages are recommended by at least `network-manager` and possibly `ifupdown`: vlan bridge-utils ifenslave -- 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/1519120 Title: NetworkManager VLAN support fails unless vlan package is manually installed Status in network-manager package in Ubuntu: Confirmed Status in vlan package in Ubuntu: Invalid Bug description: I tried to use the network manager UI to define a VLAN interface, and nothing happened. There are a few bugs here: (1) When creating a VLAN interface through the UI, the "vlan interface name" must be filled in. This should just default to <interface- name>.<vid>, rather than being a required field. (I typed in "vlan100" to get the "Save" button to activate.) (2) After creating my VLAN interface, nothing happened. No new interface appeared. I then realized that I had not installed the "vlan" package, and assumed that NetworkManager therefore could not complete configuration of the interface. (3) After installing the 'vlan' package (and then telling NetworkManager to disconnect and reconnect my Ethernet interface from the UI, just for good measure), still no VLAN interfaces were present on my system. I also tried editing the VLAN interface in the UI, and specifying "enp4s0f1.100", but still no VLAN interface came online. # apt-cache policy network-manager network-manager: Installed: 1.0.4-0ubuntu6 Candidate: 1.0.4-0ubuntu6 Version table: *** 1.0.4-0ubuntu6 0 500 http://172.16.42.88/ubuntu/ xenial/main amd64 Packages 100 /var/lib/dpkg/status # apt-cache policy vlan vlan: Installed: 1.9-3.2ubuntu1 Candidate: 1.9-3.2ubuntu1 Version table: *** 1.9-3.2ubuntu1 0 500 http://172.16.42.88/ubuntu/ xenial/main amd64 Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1519120/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
