Ubuntu 19.10 don't have official Docker support so should add it manually:

Add docker repository:
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   disco \
   stable"

Update packages:
sudo apt-get update

Install Docker:
sudo apt-get install docker.io

After steps above Docksal can be installed as usual.
