Your aptitude variant will also list new packages to be installed (e.g., a
package with a version number in its name like libperl5.24).

Otherwise you could try a search pattern of aptitude. This ability of aptitude
is one of the advantages of aptitude IMO.

  PKGNAMES=$(aptitude -F '%p' --allow-untrusted search '~U' | sort)

just do what you want? Also, it seems to be faster.
