Was trying to install "unity-tweak-tool" and get:
$ sudo apt-get install unity-tweak-tool
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
unity-tweak-tool : Depends: unity-webapps-common but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Did some research and ran:
sudo apt-get --fix-broken install
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 1 not to upgrade.
then
sudo apt-get dist-upgrade
but to no effect, so still got the problem of finding a way to backtrack to the cause of the dependencies. So tried aptitude and got:
sudo aptitude install unity-tweak-tool
The following NEW packages will be installed:
libhardware2{a} libhybris{a} libhybris-common1{a} libmedia1{a}
liboxideqt-qmlplugin{a} liboxideqtcore0{ab} liboxideqtquick0{a}

No packages will be installed, upgraded, or removed.
0 packages upgraded, 0 newly installed, 0 to remove and 0 not to upgrade.
Need to get 0 B of archives. After unpacking 0 B will be used.
Attempting to work back through the dependencies, by installing manually also ran into issues with "libqt5core5a" when running aptitude install liboxideqtquick0 wanting to uninstall libmlt++3, libmlt6, libqt5webchannel5, melt, openshot, python-mlt and qt5-gtk-platformtheme.
Any help tracking down a solution very much appreciated.

Further to request for further info:
As there is some major lags in pkgs getting updated, the following have been added to get the latest versions of pkgs or install pkgs not in the main repositories. So, to be comprehensive I include the following.
I used a script to extract a list of the repos and PPAs:
The following are self explanatory:
'http://archive.ubuntu.com/ubuntu xenial main restricted'
'http://archive.ubuntu.com/ubuntu xenial-updates main restricted'
'http://archive.ubuntu.com/ubuntu xenial universe'
'http://archive.ubuntu.com/ubuntu xenial-updates universe'
'http://archive.ubuntu.com/ubuntu xenial multiverse'
'http://archive.ubuntu.com/ubuntu xenial-updates multiverse'
'http://archive.ubuntu.com/ubuntu xenial-backports main restricted universe multiverse'
'http://archive.canonical.com/ubuntu xenial partner'
'http://archive.ubuntu.com/ubuntu xenial-security main restricted'
'http://archive.ubuntu.com/ubuntu xenial-security universe'
'http://archive.ubuntu.com/ubuntu xenial-security multiverse'
'http://deb.torproject.org/torproject.org xenial main'
'https://dl.winehq.org/wine-builds/ubuntu/ xenial main'
'https://download.virtualbox.org/virtualbox/debian xenial contrib'
These are to get the latest versions OR add functionality:
ppa:stebbins/handbrake-releases
ppa:maarten-baert/simplescreenrecorder
ppa:webupd8team/nemo3 # latest version of nemo file browser
ppa:linrunner/tlp
ppa:mc3man/mpv-tests
ppa:elementary-os/stable
ppa:bablu-boy/nutty
ppa:jfi/ppa
ppa:audio-recorder/ppa
ppa:noobslab/themes
ppa:hda-me/zulucrypt
ppa:scribus/ppa
ppa:plushuang-tw/uget-stable
ppa:mc3man/xerus-media
ppa:unit193/encryption
ppa:noobslab/icons
ppa:jeffreyratcliffe/ppa
'http://repo.vivaldi.com/stable/deb/ stable main' # Vivaldi Web Browser
===========
Now a detailed list of the installed pkgs from the PPAs, which I extracted using the following script:
apt-cache policy $(dpkg --get-selections | grep -v deinstall$ | awk '{ print $1 }') | perl -e '@a = <>; $a=join("", @a); $a =~ s/\n(\S)/\n\n$1/g; @packages = split("\n\n", $a); foreach $p (@packages) {print "$1: $2\n" if $p =~ /^(.*?):.*?500 http:\/\/ppa\.launchpad\.net\/(.*?)\s/s}'
