I am new with Linux so I choose ubuntu, but I can't use my wi-fi. I searched and tried sudo apt update and sudo apt upgrade but nothing happened and it still not working....

I also tried lspci -nnk | grep 0280 -A3 and got this ...

This is a common problem, look at the answer provided here Installing/Uninstalling WiFi Drivers on Ubuntu

Basically you need to download and build the driver for for the Realtek wireless network card from this repo: https://github.com/lwfinger/rtw88

Install the drivers

git clone https://github.com/lwfinger/rtw88.git  
cd rtw88  
make  
sudo make install
sudo modprobe rtw_8822ce

And if still in trouble, try command, since there might be conflicting drivers.

echo "blacklist ideapad-laptop" | sudo tee -a /etc/modprobe.d/blacklist.conf

And reboot.
