Based on this

Install driver rtl8814au on ubuntu 18.04

I installed manually (make && make install) the driver when I had the kernel

$ uname -r
5.4.0-26-generic

Now, ubuntu 20.04 wants to install the new one:

linux-image-5.4.0-29-generic

I did it before (upgrade the system then, the kernel) and the driver stopped to work, even I installed thousand times, was impossible to up the driver which logical name is "wlx50c4ddcf488e".

The installation I made:

$ sudo apt install build-essential
$ sudo apt install bc
$ sudo apt install linux-headers-`uname -r`
$ sudo apt install git

$ git clone https://github.com/aircrack-ng/rtl8812au.git

$ cd rtl8812au
$ make && sudo make install

Does anyone has idea about what can I do? Now, I cannot upgrade my system without losing the wireless connection.

Thank a lot.

  • Uninstall your current manually built driver, and then see the accepted answer at askubuntu.com/questions/1185952/… which builds the same driver using dkms. First install dkms if you don't already have it installed. – heynnema May 15 at 20:04
