I apparently completely misunderstood your post.
I have corrected the issue though you likely have solved that by now...
I have corrected the older post to have current up to date information which are as follows:
sudo apt-get install conky-all
sudo add-apt-repository ppa:tomtomtom/conky-manager
sudo apt update && sudo apt-get install conky-manager2
Or
sudo apt update && sudo apt-get install conky-manager2
