Help please, Cant install or upgrade anything.

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.
