Try to build without dkms (via make command) and upload build log

[mariarti]

Consult /var/lib/dkms/rtl8812au/5.2.20.2/build/make.log for more information. from previous post.
dkms-install-log.txt

and build without dkms
make.txt

[svpcom]

Try svpcom/rtl8812au@84cacef or latest master

[svpcom]

Try build without dkms

[mariarti]

make-18-05-24.txt

[svpcom]

Make succeeded. So you need to cleanup dkms sources (something like dkms uninstall or manually remove /usr/src/rtl8812au-5.2.20.2)

[mariarti]

dkms.txt

[svpcom]

Now dkms-install.sh should work

[mariarti]

Yes, finally it performed without an errors.
