rtl8822bu-dkms: Module Fails to Build on Recent Kernels and Lacks Proper Dependencies

[BlindRepublic]

System

• xuname: Void 5.13.19_1 x86_64 GenuineIntel uptodate rFFFFF

• package:
  affected package(s) including the version: rtl8822bu-dkms-20201222_1

Expected behavior

The module compiles and properly enables Wifi with the adapter.

Actual behavior

The compilation of the module fails due to not having bc installed and gets farther into the process after installing the package before failing once more.

There are other repositories on Github that seem to have a working driver with recent kernels. The following have worked for me:

• https://github.com/RinCat/RTL88x2BU-Linux-Driver (packaged in the AUR)
• https://github.com/morrownr/88x2bu.git

Error in module build process with bc installed:
