Probelms with Loading Realtek rtl8812AU driver in Ubuntu 19.10
I'm having the same issue but after distribution upgrade now on kernal 5.3.0-26-generic. sudo apt install rtl8812au-dkms
had always worked after new kernel upgrade but not now so your not alone.
Ok after some searching this worked for me:
sudo apt install git dkms
git clone https://github.com/aircrack-ng/rtl8812au.git
cd rtl8812au
sudo make dkms_install
Got my answer from here maybe it helps Need rtl8814au driver for kernel 5.3 on Ubuntu 19.10
The person posting answer also said this:
It worked for me on my rtl8814au device, it should work for rtl8812au, rtl8814au, and rtl8821au devices. For some strange reason the driver didn't want to work until after a second reboot. I don't know why
Hope it helps.

I have a Asus USB-AC53 Nano wifi adapter that has stopped working after a recent ubuntu software update. The adapter still works on other machines.
I am on 19.10 and the output of uname -a is:
jon@jon-basemet:~$ uname -a Linux jon-basemet 5.3.0-26-generic #28-Ubuntu SMP Wed Dec 18 05:37:46 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
DKMS Status:
sudo dkms status nvidia, 390.129, 5.3.0-24-generic, x86_64: installed nvidia, 390.129, 5.3.0-26-generic, x86_64: installed rtl8812au, 4.2.2, 5.3.0-26-generic, x86_64: installed
I followed these two sets of instructions:
sudo apt update sudo apt install git git clone https://github.com/gnab/rtl8812au.git sudo cp -r rtl8812au /usr/src/rtl8812au-4.2.2 sudo dkms add -m rtl8812au -v 4.2.2 sudo dkms build -m rtl8812au -v 4.2.2 sudo dkms install -m rtl8812au -v 4.2.2
and
sudo apt-get purge rtl8812au-dkms sudo apt-get install git git clone https://github.com/jeremyb31/rtl8812AU.git sudo dkms add ./rtl8812AU sudo dkms install rtl8812AU/5
Neither of these solutions worked.

Running journalctl --follow and inserting the Asus antenna (without the edimax one installed) gives the following:

CHsurfer over 4 yearsThanks for this suggestion, but unfortunately it didn't work for me. I removed the last drive I tried from dkms, erased the source files and then followed your instructions. The driver installed with no warnings but after a reboot, my usb antenna is still not recognized.

CHsurfer over 4 years@Jeremy31 Thanks for pointing this out. Not sure how I came to the idea that it was a RTL8812AU. I tried your driver, but it did not work either...
