I am running a live installation of Ubuntu 20.04 LTS with Persistent Storage of 40GB. For some reason I can not install anything without getting the error Unable to correct problems, you have held broken packages. (see full output below). For instance, I am trying to install Keepass2. I have added the repositories sudo apt-add-repository ppa:jtaylor/keepass, I have updated apt sudo apt-get update && sudo apt-get upgrade, and yet when I run sudo apt-get install keepass2 -y I still get that same error! I did almost exactly the same process when trying to install i2p, and I also got the broken packages error. I also can not open the Ubuntu Software app.
Full Output of sudo apt-get install keepass2 -y:
