Ubuntu 16.04 and Up Terminal Installation
Follow this link for Bookworm: https://babluboy.github.io/bookworm/
Otherwise, here are the terminal commands to satisfy any dependencies from the Git-Hub repository site:
sudo add-apt-repository ppa:bookworm-team/bookworm
sudo apt-get update
sudo apt-get install com.github.babluboy.bookworm
Be very certain to install the first repository above and update your sources before you proceed to the commands below.
Note that you cannot install Bookworm without adding the Elementary OS repository and updating your sources to satisfy your dependencies.
Install Bookworm only after adding the Elementary OS repository following the terminal commands below.
sudo add-apt-repository ppa:elementary-os/stable
sudo apt-get update
sudo apt-get install com.github.babluboy.bookworm
Let me know how this works out for everyone present.
