As for ppa install, I might be doing something wrong: (Linux Mint 19 = Ubuntu bionic)
sudo add-apt-repository ppa:kwant-project/ppa sudo apt-get update sudo apt-get install kwant
returns: "Unable to locate package kwant"
Kwant 1.3.3 and Tinyarray packages are available for Ubuntu bionic: https://launchpad.net/~kwant-project/+archive/ubuntu/ppa/+packages
No idea what's going wrong with your installation of Linux Mint 19.
