Cant boot Ubuntu after upgrading to nvidia-515

Hi everyone

I just run the following command
sudo apt install nvidia-driver-515

And after restart Ubuntu is not entering on graphical interface.
I have access only on tty

Sorry the images, I cant send the log cause the network is down.

Can you help me?
A lot of time working on it but no results
Thanks very much

Looks like the driver for your igpu is missing/disabled. If you set “nomodeset” kernel parameter, please remove it. Which cpu model do you have? Which kernel version is running? Which Ubuntu version is running?
