The official docker documentation recommend to use

  $ sudo add-apt-repository \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

for Ubuntu 19.10 which seems that doesn't contain 'containerd.io' package yet.

Remove the previously added repository using add-apt-repository --remove :

$ sudo add-apt-repository --remove \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

and add the one used for bionic (18.10) Ubuntu release:

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

After this, update and install docker:

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io
