I need help with a command for Kali Linux, the "apt-get"

Hello to all.

I use the last version of Kali Linux on Sunday
August 14, ( Yes I don't know the current version of Kali Linux... ) My computer is in x64Bit.

I have in front of me a problem of comprehension because
I can't execute some basic commands like the "apt-get"...

It's really annoying...

I think I have the administrator rights with the command I have done which is: "sudo passwd root". But the command I have done is: "sudo apt install gnome-tweak-tool".
( gnome-tweak-tool is an application that allows to make more aesthetic Kali Linux )
I also tried some variants... with : "apt-get install gnome-tweak-tool".
I run my commands in the root version of Kali Linux. ( I don't know if this information is useful but just in case )

The apt-get command does not work for any application or extension installation...

I thank you for your answer in advance;

Thank you very much,

Jim007o ;)

Before you can apt-get install anything you need to update the repositoiry

sudo apt-get update
sudo apt-get full upgrade -y

Hello Fred Sheehan,
I have already done this order... I should do it again just to make sure I did it right.
After all, I have nothing to lose.




Best regards,

There is no gnome-tweak-tool listed in the repository.

Code:

---

apt search tweak tool
*snip*
gnome-tweaks/kali-rolling 42-beta-1 all
tool to adjust advanced configuration settings in GNOME

Is gnome-tweaks what you were trying to install?
