Link: https://github.com/k82cn/rtl8821ce. I cloned it, and used make && make install.(it compiled successfuly)

OS: Ubuntu 18.04

  • What is the issue? Did you get an error when loading the module (please post the error)? Did you get an error when running make install (because you should have used sudo make install)? – mchid Oct 17 at 7:19

I solved it by turning Secure Boot off in the BIOS.
