Public bug reported:
Distro: Ubuntu 16.10
MAAS version: 2.1.2+bzr5555-0ubuntu1~16.10.1 500
For some node MAC addresses (I have a relatively old servers) I am
unable to open MAAS dashboard page or Nodes page due to
"list index out of range"
error.

builtins.IndexError: list index out of range
For now I have worked around the issue by catching IndexError in
"/usr/lib/python3/dist-packages/maasserver/utils/mac.py". After this
workaround the Nodes page started working but Dashboard page required
similar fix in "/usr/lib/python3/dist-
packages/provisioningserver/utils/network.py" in line 923
But this probably needs some investigation and fix - without the
workaround I cannot use MAAS.
** Affects: maas (Ubuntu)
Importance: Undecided
