Last year, I had successfully installed conky and conky-manager in Freya. Now I have migrated to Juno. I am very happy with this new version. But I would like to install also conky and conky-manager. I know it's not easy, but you can, and I have not found complete and effective instructions on the internet.
First of all download files from following links:
And then go to your download directory use following commands in your terminal:
sudo apt install conky
sudo dpkg -i realpath_8.26-3ubuntu4_all.deb conky-manager-v2.4-amd64.deb
sudo apt -f install
Enjoy!
