I don`t understand why suddenly i can not install anything or make parrot-upgrade. Help me to solve this please!
Hi. Your first screenshot shows you used
sudo apt-get install
That will break your Parrot install.
sudo apt install
is the method to install software on Parrot. And
sudo parrot-upgrade
is the method to update Parrot.

Try using
sudo apt update --fix-missing
sudo apt install -f
sudo apt clean
sudo apt autoremove
sudo dpkg --configure -a
sudo parrot-upgrade
If all goes OK, then you can
sudo apt install build-essential checkinstall

You have to provide basic information so everybody can help you.
First: your version of Parrot OS
second: What did you install before run Parrot upgrade.
