Comment 32 for bug 241368

I think you refer to this line:
      new=`dpkg -l | grep ^ii | grep $ver |grep linux-| awk -F' ' '{ print $2 }'|xargs`
which identifies all the packages involved with a particular kernel version.
In this case, searching (with grep) for linux- instead of linux-image- has the same effect, unless you see otherwise (in which case, please show the commands as well as the filtered and unfiltered (before and after grep) outputs).
