I'm new using docker and linux and I tried to install docker on my new Ubuntu 20.04 LTS.
I was following these instructions: https://www.digitalocean.com/community/tutorials/how-to-install-and-use-docker-on-ubuntu-20-04
When I arrived at this command:
sudo apt install docker-ce, I got this error:
Reading package lists... Done Building dependency tree Reading state information... Done docker-ce is already the newest version (5:19.03.9~3-0~ubuntu-focal). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 1 not fully installed or removed.

Can someone help me to resolve this ?
For learning purposes, I would like to know what is going wrong and why. But isn't mandatory as long as this works again.
Thank you very much.
