  # This command runs after all other steps; it:
  # 1. Disables swapfiles
  # 2. Removes the existing swapfile
  # 3. Removes the swapfile entry from /etc/fstab
  # 4. Removes snapd, https://bugs.launchpad.net/subiquity/+bug/1946609
  # 5. Cleans up any packages that are no longer required
  # 6. Removes the cached list of packages
