Unable to locate linux-kernel

[JacquesRoubaud]

Hi I am trying to use a second wifi dongle (TP link Archer T3U AC1300), and the driver is not recognized. I am following this procedure : https://community.tp-link.com/en/home/forum/topic/208022 git clone https://github.com/cilynx/rtl88x2bu.git cd rtl88x2bu VER=$(sed -n 's/\PACKAGE_VERSION="(.*)"/\1/p' dkms.conf) sudo rsync -rvhP ./ /usr/src/rtl88x2bu-${VER} sudo dkms add -m rtl88x2bu -v ${VER} sudo dkms build -m rtl88x2bu -v ${VER} sudo dkms install -m rtl88x2bu -v ${VER} sudo modprobe 88x2bu

Note that VER = 5.8.7.1

when I run sudo dkms build -m rtl88x2bu -v ${VER}, I have an error message that says Error! your kernel headers for kernel 5.4.70-g78d1314be027-dirty cannot be found. Please install the linux-headers-5.4.70-g78d1314be027-dirty package I have spent a few hours googling possible solutions, but every time, in a way or another , I am blocked by the fact that the linux header cannot be found.

Is there anything special in the linux installation of the PC ? Any clue ?

thank you Jacques

Hi @JacquesRoubaud,

You're right. In order to install a new driver, you need to compile it and have linux headers installed. I confirm that the package linux-headers-5.4.70-g78d1314be027-dirty is not available.

I will check with the manufacturer (TechNexion) if the package exists or if a kernel upgrade is necessary.

Acutually, only the 8192eu driver is available.
