That is NOT the name of any driver in this repo.

I have gone through this link and only this driver is mentioned here to install wifi package.
Please help me out with this, I am not able to use wifi.

Are you sure you have an RTL8723DE? Use 'lspci -nn' to verify that.

The driver names in THIS repo are rtw_8723de.ko rtw_8723d.ko rtw_8821ce.ko rtw_8821c.ko rtw_8822be.ko rtw_8822b.ko rtw_8822ce.ko rtw_8822c.ko rtw_core.ko rtw_pci.ko

Apparently you are using instructions that refer to an old repo and not looking at what is here.

If you have successfully done
make
sudo make install
sudo reboot

once the system comes up, the wifi should work.

Nope its not working either.

this is the output of lspci -nn

In your lspci output is "Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac", thus you have an 8822be. If you look at my previous comment, that driver is found in this repo. Do the "make" sequence I gave you.

[naveenthakur0225]

(base) naveen@nv:/rtw88$ sudo modprobe -r rtw_8822be
(base) naveen@nv:/rtw88$ sudo modprobe rtw_8822be
modprobe: ERROR: could not insert 'rtw_8822be': Operation not permitted

I think this is the last error I am getting.

Do you have secure boot enabled? That would prevent loading an external module.
