So as per the instructions, I've already added the ppa repo, and updated. But when I run:
# apt install dde

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

E: Unable to correct problems, you have held broken packages.
Is there a fix to this?
Edit: I have already tried the aptitude and synaptic methods. Aptitude reduced my dependencies by maybe 2, and synaptic says that I need to fix broken packages first. When trying the commands sudo dpkg -l | grep ^..r and apt-mark showhold I get no results.
Edit 2: I have tried the solutions from the second duplicate claim too, no luck.
