Eu testei isso usando duas máquinas virtuais executando o Lubutu.
No primeiro eu instalei alguns programas (VIM e cowsay) e então corri:
sudo apt-get update
sudo apt-get upgrade
sudo dpkg --get-selections > /home/klak/my_package_list.txt
Veja como o my_package_list.txt se parece
Em seguida, inicializei em outra VM que era um clone do anterior, antes das instalações do VIM e do cowsay, e executei o seguinte:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install dselect
sudo apt-get dselect update
sudo dpkg --set-selections < ./my_package_list.txt && sudo apt-get -u dselect-upgrade
No entanto, eu esperaria agora poder carregar o VIM ou usar o cowsay, mas recebo:
klak@klakBox:/media/share$ vim
The program 'vim' can be found in the following packages:
* vim
* vim-gnome
* vim-tiny
* vim-athena
* vim-gtk
* vim-nox
Try: sudo apt-get install <selected package>
klak@klakBox:/media/share$ cowsay "boo"
The program 'cowsay' is currently not installed. You can install it by typing:
sudo apt-get install cowsay
Ele passou por um processo de carregamento de instalação quando eu executei os comandos acima, então não sei por que isso não funcionou.
Felicidades!

Não tenho certeza do motivo desses erros (parece ser uma opção dselect válida):
klak@klakBox:/media/share$ sudo apt-get dselect update
E: Invalid operation dselect
klak@klakBox:/media/share$
Editar 1.1
Existe um menu CLI para o dselect, se eu inserir sudo dselect , não sei como incluir isso em um script.
Neste menu eu escolhi update (como a tentativa anterior de atualização falhou)
- Nota - > a primeira vez que executei
sudo dselect update foi de um script python usando os.system("sudo dselect update") - > Talvez isso tenha errado silenciosamente, não sei.
Editar 2
Eu usei o seguinte ( tirado daqui )
dpkg --set-selections < selections.txt
$ sudo apt-get install dselect
$ sudo dselect
-> Update
-> Install
A atualização e instalação do dselect são de dentro de um menu CLI:

Este é o script python que funciona:
os.system("sudo apt-get install dselect")
os.system("sudo dselect update")
os.system("sudo dpkg --set-selections < my_package_list.txt")
os.system("sudo apt-get -y update")
os.system("sudo apt-get dselect-upgrade")
Obviamente, antes que isso seja executado, é necessário que tenha sido criada uma lista de pacotes chamada my_package_list.txt , e ela precisa estar no mesmo diretório que o arquivo Python.
