The error in your logs is:

dpkg: error processing package shim-signed (--configure):
 subprocess installed post-installation script returned error exit status 1

This indicates that the debconf frontend was shut down before you could
be prompted for disabling secureboot on your system, which is required
for dkms modules.

How did you go about installing the rtl8812au driver package?  Did you
select this from the "Additional Drivers" dialog of Software & Updates?

To complete the installation of this package, you will want to run 'sudo
apt -f install' from a terminal.
