Best Answer

On my Xenial system I can install unity-tweak-tool from universe repository and it works normally.

So I recommend to purge its PPA and install version from repository with

sudo apt-get update
sudo apt-get install ppa-purge

sudo add-apt-repository main # add main repository for sure
sudo add-apt-repository universe # add universe
sudo add-apt-repository multiverse # add multiverse
sudo add-apt-repository restricted # add restricted

sudo add-apt-repository -r ppa:upubuntu-com/gtk3 # to fix apt-get update

sudo ppa-purge ppa:freyja-dev/unity-tweak-tool-daily

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install -f
sudo dpkg --configure -a

sudo apt-get install unity-tweak-tool

If all these steps do not help try to switch to other Ubuntu mirror from Software & Updates.

You can try aptitude too (installable with sudo apt-get install aptitude)

sudo aptitude install unity-tweak-tool
