RTL88x2bu Driver for new Kernel Version

Just yesterday, I installed Cilynx Driver for my new tp-link Archer TU3 Plus (AC1300) and it worked just fine. (I used lsusb to determine my Adapters USB ID, which is 2357:0138 and the internet said it is an RTL88x2bu chipset.)

Today I did a release upgrade, and had no connection afterwards. I then tried to used an answer on how to remove the driver and tried to reinstall the driver, but it failed. Error when trying to remove old driver:

Error occurring during the reinstallation:

user@t:~/Downloads/rtl88x2bu$ sudo dkms build -m rtl88x2bu -v ${VER}

Kernel preparation unnecessary for this kernel.  Skipping...

make -j4 KERNELRELEASE=5.8.0-26-generic KVER=5.8.0-26-generic src=/usr/src/rtl88x2bu-5.6.1...(bad exit status: 2)
Error! Bad return status for module build on kernel: 5.8.0-26-generic (x86_64)
Consult /var/lib/dkms/rtl88x2bu/5.6.1/build/make.log for more information.

I also tried this way, but again I get an error:

Pleas help me to get the driver running again!

Solution 1:

Please verify that you have removed all other instances of the driver:

sudo dkms status

Next, do:

git clone "https://github.com/RinCat/RTL88x2BU-Linux-Driver.git" /usr/src/rtl88x2bu-git
sudo sed -i 's/PACKAGE_VERSION="@PKGVER@"/PACKAGE_VERSION="git"/g' /usr/src/rtl88x2bu-git/dkms.conf
sudo dkms add -m rtl88x2bu -v git
sudo dkms autoinstall

Reboot.
