Не удается установить ia32-libs на 64-битную версию Ubuntu 14.04?

Я пытаюсь установить Adobe Air, но для этого мне нужно установить ia32-libs.

Я попробовал несколько предоставленных решений, но ни одно из них на самом деле не сработало.

jakub@jakub-home:~/Downloads$ sudo apt-get install ia32-libs

Package ia32-libs is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  lib32z1 lib32ncurses5 lib32bz2-1.0

E: Package 'ia32-libs' has no installation candidate

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 adobeair : Depends: ia32-libs-gtk but it is not installable or
                     devolo-ia32-libs but it is not installable
 lib32bz2-1.0 : PreDepends: libc6-i386 (>= 2.9-18) but it is not going to be installed
 lib32ncurses5 : Depends: lib32tinfo5 (= 5.9+20140118-1ubuntu1) but it is not going to be installed
                 Depends: libc6-i386 (>= 2.4) but it is not going to be installed
 lib32z1 : Depends: libc6-i386 (>= 2.4) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Я попробовал несколько решений, найденных здесь, только один пример из здесь :

jakub@jakub-home:~/Downloads$ sudo dpkg --add-architecture i386 && sudo apt-get update && sudo apt-get install ia32-libs

Здесь должна быть некоторая фундаментальная проблема. Может ли кто-нибудь помочь мне разобраться?
