Pimp my parrot bash script

Hello,
I use parrot OS for a few month and was very satisfied with it.
The trouble began when I upgraded the system using the bash script pimp my parrot. The system failed.

I recently read that the apt-get upgrade shouldn’t be used on parrot OS, but parrot-upgrade instead. The script contains this command and I think that is the cause of the OS getting stuck.

Have some of you experienced similar issues while running pimp-my-parrot ?

Greetings, Marc
