I installed xanmod kernel and solved the error "bad exit status: 2) ERROR (dkms apport): kernel package linux-headers-5.4.18-xanmod10 is not support ed Error! Bad return status for module build on kernel: 5.4.18-xanmod10 (x86_64)" with:

sudo add-apt-repository ppa:canonical-hwe-team/backport-iwlwifi

sudo apt install backport-iwlwifi-dkms

But no wireless card yet. Any other suggestion?

  • yes i will try, but i don't think this is the problem. thnx – djazz Feb 15 at 1:29
  • Hi, i installed xanmod kernel and nothing to do, no wireless extensions. However during kernel installation there were one error: "'make' -j4 KLIB=/lib/modules/5.4.18-xanmod10.................................... ...............(bad exit status: 2) ERROR (dkms apport): kernel package linux-headers-5.4.18-xanmod10 is not support ed Error! Bad return status for module build on kernel: 5.4.18-xanmod10 (x86_64) Consult /var/lib/dkms/backport-iwlwifi/7906/build/make.log for more information" – djazz Feb 15 at 12:28
