This is curious. The error message indicates that the "policy-rc.d" mechanism is used to prevent daemons from starting. And indeed:
```
# cat /usr/sbin/
#!/bin/sh
echo "All runlevel operations denied by policy" >&2
exit 101
```
However this file is not owned by any package:
```
# dpkg -S /usr/sbin/
dpkg-query: no path found matching pattern /usr/sbin/
```
and nothing in /var/lib/dpkg/info seems to create policy-rc.d.
The file was last modified "Feb 11" but nothing else in {,/usr}/{,s}bin has a similar timestamp.
```

So maybe a side-effect of the ubuntu-advantage install or the script that did that install forgot to cleanup something?
