That looks a bit worrying.  It feels as if maybe some sort of clear
out and re-installation might clear things up, but I'm not quite sure
what.
 

The fix turns out to be fairly simple.  You go and find the file which
has the missing newline (probably due to an interrupted download or
some such) and remove it.  The dpkg files in question are in directory
/var/lib/dpkg/info.  Once removed simply 'apt reinstall' the package
and all is well again.

I found the solution on an ubuntu list.
