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

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.
