On Debian 11, `ipset` just recommend `iptables` so on the system that apt is configured with `APT::Install-Recommends "0";` iptables will not install automatically.
- Use python3-apt instead because python-apt was removed in Debian 11 - Add gnupg (fix "container-engine/containerd : ensure containerd repository public key is installed" task failed) - Remove aufs-tools Signed-off-by: rtsp <git@rtsp.us>
