  • I have installed Ubuntu 18.04 in my Lenovo laptop.
  • It does not show up the WiFi options.
  • I tried downloading the drivers and installing them in the way as described here Wi-Fi not working on Lenovo ThinkPad E570 (Realtek RTL8821CE). But nothing in use.

  • Whenever i try to use make command, I get

    /bin/sh: 1: cc: not found

EDIT 1

  • After installing build-essential also the problem exists with the error.

EDIT 2 - I have upgraded my kernel to 4.18.6 and also installed libelf-dev. Again when I enter make command. It gives

  • The make command reports gcc is missing. If you want to compile the driver, install build-essential package. – minish Nov 16 '18 at 04:45
  • Before going further, are you sure you have the exact same device? Even same models can come with different WiFi cards (and other parts, of course). –  Nov 16 '18 at 10:06
  • I suggest that you: sudo apt install libelf-dev and try again. – chili555 Nov 16 '18 at 14:36

You need to get the build-essentials package. Use the command

sudo apt install -y build-essential
