    Go to the terminal and run sudo apt update (type your password) then sudo apt upgrade. Then try installing Synaptic again.

Run the following commands in your terminal (Ctrl+Alt+t):

sudo apt clean
sudo apt update
sudo apt upgrade
sudo apt -f install
sudo apt install synaptic

When prompted, enter your password. This should install synaptic for you, along with clearing up broken packages (fixing dependency issues) and updating your system.

Special thanks to @DKBose for pointing out sudo apt clean. :)

  • @DKBose, excellent thoughts, thanks for pointing out. :)

    @DKBose, it's still there: I'm guessing it's an oversight in the documentation.
