Hi, you need post /var/lib/dkms/rtl88x2bu/5.8.7.1/build/make.log that actually show the error.

thanks. just done

[RinCat]

You are using 5.8.7.1? That a 5 years old version. Update the version should works.

You are using 5.8.7.1? That a 5 years old version. Update the version should works.

hi. this was part of the system image for the raspberry. so should I manually remove the current installed drivers with
sudo dkms remove -m ..

and clone down the repo and install fresh like described here?
https://askubuntu.com/questions/1288547/rtl88x2bu-driver-for-new-kernel-version

thanks a lot

[RinCat]

Yes, you can also check the README
