Ubuntu failure to upgrade

I just downloaded the latest release (16.12.11) and the Ubuntu Software Centre is reporting a bad package.

Ubuntu 16.04, AMD64

Ubuntu’s software centre will do that to you sometimes.
Most of the time, it is simply referring to a lack of compliance with Debian’s strict policies about non-free binaries. That said, we can run the lintian command on the Manager.deb file to see what it is that it does and doesn’t like.
I have just downloaded the latest Manager.deb and run linitian -i and here is the output:-

_$ lintian -i Manager.deb_

Personally speaking, I do not see anything there that worries me unduly - sure it could be a bit tidier here and there, but hey…
