    # Purging docker using `sudo snap remove docker --purge` did not even work.
    # These were the only steps that worked:
    #
    # 1. Stop docker: `sudo systemctl stop docker`.
    # 2. Delete the networking database: `sudo rm /var/lib/docker/network/files/local-kv.db`.
    # 3. Start docker: `sudo systemctl start docker`.
    #
    # For this reason, this will _stay_ commented out.
