Unable to install Unity tweak tool in Ubuntu 16.04?

[maxyspark]

I had Installed "Unity Tweak Tool". But now it disappeared.


When I tried to install again it shows the following output

sudo apt-get install unity-tweak-tool

I am having the same issue. Were you able to find a solution?

Try install unity-webapps-common first


sudo apt install unity-webapps-common

That seems to just lead to another package that wont install. Then when trying to install that package, it throws another
package that wont install. (see below) I went about 7 dependencies deep and it does the came thing every time.

Also this seems to be the only package that has problems installing. Everything else i have installed is working fine.

Let's try this way:


sudo apt -f install

Make sure the Canonical Partners repository is enabled in Software & Updates under other software. Then try the following and if there are no errors try and install again.


sudo apt update
sudo dpkg --configure -a
