Lenovo Thinkpad E480 - No Wifi Adaptor Found in Ubuntu 18.04
With a temporary working internet connection by ethernet, tethered or any other means, open a terminal Ctrl+Alt+t and do:
sudo apt update
sudo apt install build-essential git dkms
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh
The file builds for me on my 18.04 system with a few possibly harmless warnings but no errors.
Follow with:
sudo modprobe 8821ce
You should be all set.

I have recently a purchased Lenovo Thinkpad E480 laptop, I have installed Ubuntu 18.04 on it, everything is working fine except am not able to connect to network via WiFi. Please help.
I followed this link, but am unable to solve the issue.
Below are the outputs of some commands.

It seems I have to clone, compile and install the required WiFi driver, please guide me which WiFi driver to use and how to install (with steps if possible).
P.S.: Let me know if any further information is needed to solve this issue, I will add the required info (if any) in the question as per the guidance given.
