Actually, in hindsight after renaming the bug, it looks like there are two bugs identified here. 1) NetworkManager does not depend on or recommend the vlan package, and silently breaks when it isn't installed; and 2) from comments 4 and 5, there is a separate issue with a glob match for NICs in ifupdown.
Since Mike filed this bug originally, I think it makes sense to track this bug as the first issue. For the second issue, SwaJime and Arnaud, please could you use a separate bug to track this? It's the second issue I spotted that caused me to assign Wes this bug, but thank you for looking at the NetworkManager GUI issue too! One complication is that this change would pull vlan onto a bunch of CD images. I'd like feedback from the release or SRU teams before sponsoring this. Or, Mathieu, as this is Network Manager related, would you mind chiming in please? -- You received this bug notification because you are a member of Desktop 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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
