Answer 1

There is a bug in zsys here: https://bugs.launchpad.net/ubuntu/+source/zsys/+bug/1886214.

One solution is to do this:

1. Enable proposed branch in your repository and update.

$ echo "deb http://archive.ubuntu.com/ubuntu/ $(lsb_release -cs)-proposed main" | sudo tee /etc/apt/sources.list.d/proposed-repositories.list
$ sudo apt update

2. Install zsys v0.4.7 (as of today, 10 Aug 2020) by:

$ sudo apt -t $(lsb_release -cs)-proposed install zsys

3. Remove the proposed branch if you don't want it to stay:

$ sudo rm /etc/apt/sources.list.d/proposed-repositories.list
$ sudo apt update
