I am running VERSION="20.04.3 LTS (Focal Fossa)" The most recent software update may have disabled my USB wifi driver. I wanted to re-install the driver as the answer in this Q instructs https://askubuntu.com/questions/1312297/usb-wifi-adapter-is-not-working-on-ubuntu-20-04-1-lts(this worked for me last year). When repeating those instructions I run into this error:

step: sudo dkms build -m rtl88x2bu -v ${VER} outcome: Kernel preparation unnecessary for this kernel. Skipping...

Building module: cleaning build area... make -j8 KERNELRELEASE=5.13.0-27-generic KVER=5.13.0-27-generic src=/usr/src/rtl88x2bu-5.6.1........(bad exit status: 2) ERROR (dkms apport): binary package for rtl88x2bu: 5.6.1 not found Error! Bad return status for module build on kernel: 5.13.0-27-generic (x86_64) Consult /var/lib/dkms/rtl88x2bu/5.6.1/build/make.log for more information.

Q: Appreciate help with updating / re-installing this driver (assuming its not the antenna that went bad)

  • This probably means that the driver doesn't build with the 5.13 kernel.

I just built the most recent version of the driver in a virtual machine running Ubuntu 20.04. My kernel version, as reported by uname -r is 5.13.0-39-generic. I am using an amd64 system. So I would suspect the driver still builds on Ubuntu systems.

However, I noticed your error messages state you are using 5.6.1 as the version of the driver. This version is outdated and not updated anymore. The maintained version is 5.8.7.1 which is the available here.
