I can confirm that the proposed ubuntu-fan package resolves the issue. If you are deploying with Juju and MaaS the Ubuntu proposed repository can be installed automatically on the nodes deployed by MaaS. This could be used as a temporary workaround for the issue.
Example for how it could be set up in MaaS: https://gist.githubusercontent.com/fnordahl/f6e6b734484363e980a6e7fa2cfe51de/raw/b64d83225e0d11c1bd236e4f4625b0c466ad755f/maas-ubuntu-proposed.png -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to ubuntu-fan in Ubuntu. https://bugs.launchpad.net/bugs/1737640 Title: /usr/sbin/fanctl: arithmetic expression: expecting primary | unconfigured interfaces cause ifup failures Status in juju: Triaged Status in ubuntu-fan package in Ubuntu: Confirmed Status in ubuntu-fan source package in Xenial: Fix Committed Bug description: I'm seeing this error as the status of multiple containers in my deploy: http://paste.ubuntu.com/26166720/ I can't connect to the parent machines anymore either - it seems networking is totally hosed on the machines.
