CUDA toolkit install commad looks included wrong


I tried to install latest driver install instruction from CUDA Toolkit 12.4 Downloads

almost install componts and process is simlar with previous version.
But last cuda insttall command is bellow and failed.

sudo apt-get -y install cuda-toolkit-12-4

For my solution is change commad description

sudo apt-get -y install cuda

Regarding the Driver Installer, I used well-known command line as below.
sudo apt-get install -y cuda-drivers-550

latest , especially cuda 12.3 later cuda toolkit install command is correct??

Hope somebody’s help.
