Comment 5 for bug 1906131

Still got similar issue even trying to install linux-modules-5.10.1-051001-generic:

Building module:
cleaning build area...
KVER=5.10.1-051001-generic make...(bad exit status: 2)
ERROR (dkms apport): kernel package linux-headers-5.10.1-051001-generic is not supported
Error! Bad return status for module build on kernel: 5.10.1-051001-generic (x86_64)

   ...done.

And relevant build log:
