dpkg requires docker-ce, not installed

[timothybuchanan]

When following your instructions for placing HA on rpi using debian 11, the command
sudo -i dpkg -i homeassistant-supervised.deb gives the error that docker ce- is not installed. However, docker version says that 20.10.14+dfsgl is installed, and systemctl status says docker is active. Does the debian version of HA require an obsolete version of docker and can we get around this?
