Ubuntu – Make: *** [modules] Error 2 when trying to install rtl8723de driver


I was trying to install a wifi driver in my Ubuntu 18.04.
kernel 14.5 and hp laptop.

I ran these commands:

sudo apt-get install build-essential dkms
wget -d -c -O 'rtl8723de.zip' https://github.com/smlinux/rtl8723de/archive/4.11-up.zip
unzip rtl8723de.zip
cd rtl8723de

After make I get this output in terminal:

make ARCH=x86_64 CROSS_COMPILE= -C /lib/modules/4.15.0-22-generic/build M=/home/praveen/rtl8723de  modules

How do I solve this problem?

Best Answer

  • First, remove the inoperable files:

    sudo rm -r rtl8723de*

    Next, install another prerequisite:

    sudo apt update && sudo apt -y install git

    Now clone a better file:

    git clone https://github.com/lwfinger/rtlwifi_new.git

    Now build the driver:

    cd rtlwifi_new
    sudo make install
    sudo modprobe rtl8723de

    Your wireless should now be working.

    EDIT: When Update Manager installs a newer kernel version, also known as linux-image, after the requested reboot, recompile:

    cd ~/rtlwifi_new
    make clean
    git pull
    sudo make install
    sudo modprobe rtl8723de
