I tried everything, but still I couldn't install elementary-tweaks on Loki [duplicate]

Question

I've installed 'software-properties-common', 'python-software-properties', but still I couldn't install the 'elementary-tweaks' in Loki.

Now remember what I've installed and then when I run

sudo add-apt-repository ppa:philip.scott/elementary-tweaks

I get,

curl -sL  http://i-hate-farms.github.io/spores/install | sudo bash - 
sudo apt-get install elementary-tweaks

Hope it can help you.

You shouldn't need 'python-software-properties' to install 'elementary-tweaks'. I guess, the Python version is breaking up something. Try removing 'python-software-properties' with

sudo apt-get remove 'python-software-properties'

and then add the PPA, if it's not been already added:

sudo add-apt-repository ppa:philip.scott/elementary-tweaks

sudo apt-get update

sudo apt-get install elementary-tweaks
