So, this is a more detailed version of a post I made on Unix&Linux StackExchange, which is a repost of a (wrongfully placed) post on AskUbuntu.


So I have a WiFi-adapter that is integrated with my motherboard; Network controller: Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter and Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 16).
So after I installed GNOME, I went straight to finding WiFi drivers, and I found this package (tomaspinho/rtl8821ce).

So, I tried to install the package way:

First,

I tried the method of git clone, then manually build (using dkms-install.sh), but that produced these errors:

About to run dkms install steps...
Error! Could not locate dkms.conf file.
File: /usr/src/rtl8821ce-v5.5.2_34066.20200325/dkms.conf does not exist.
Error! Could not locate dkms.conf file.
File: /usr/src/rtl8821ce-v5.5.2_34066.20200325/dkms.conf does not exist.
Error! Could not locate dkms.conf file.
File: /usr/src/rtl8821ce-v5.5.2_34066.20200325/dkms.conf does not exist.
Finished running dkms install steps

So, I tried to find a way to fix this error( collection).
I found this post on AskUbuntu (Error! Could not locate dkms.conf file).
They used dkms-reconfigure, so brainlessly, I just followed along, and probably not to your surprise, it didn't work.
I tried looking for some kind of Arch equivalent, but there was none.

It was apparent I had to change strategy, so then,

second,

I tried installing the driver right from the AUR (Arch User Repository); rtl8821ce-dkms-git 1.0.5.r36.gca4abd8-1.
I tried installing it by doing yay -S rtl8821ce, I even tried to follow this tutorial to help me, but to no avail.

I'm very lost. I've basically tried everything (on the surface level that I could find) to get the driver(s) to work with my installation.


So, how/where can I install a driver that works with my adapter?
