I am trying to install the driver for the Realtek 8821ce in my laptop. I installed Debian 10. And I am completely without internet.
This is the solution I was following: Realtek rtl8821ce wifi driver problem in Linux Mint 18.2
I installed manually with a USB the bc utility deb package because it was returning an error. Now with the command make it works a while but in the end returns many errors. Please check the image attached.
https://github.com/tomaspinho/rtl8821ce would be the correct repo. manual how to install is in git repo. use dkms-install.sh from that git repo.
Had this error message a few days ago. In my case the error came from using a deprecated kernel header file in the source code (depending on your installed kernel header version). You might need to add the following include to your source file
#include <linux/uaccess.h>
In your case it seems not be included at all.
git clone https://github.com/brektrou/rtl8821CU.git
try this, as there is no official Linux driver for this chipset :(
rtl8821CU , But the request was for rtl8821CE, Is both similar, btwn I am newbie for linux network drivers, But I too face the same issue
