How to get RTL8814AU as Alfa AWUSB1900 working in Kubuntu?

Question

Install driver rtl8814au on ubuntu 18.04 I tried that question, it appears as if the tip for getting it to work in Kali Linux :
sudo apt-get install realtek-rtl88xxau-dkms

Yields no access to a suitable driver for the device. I've also tried various git clone repos but no go. As of now it will lock up my shut down if I plug the wireless adapter in. If I try to use any of the git clone repos it gets stuck at the depmod/modprobe and the machine also cannot shut down (it hangs the system eternally). What can I do to get this working in Kubuntu? I don't want to switch to Kali Linux because it might not support my touch screen... Also my dpkg --configure -a is required now, and it can't fix my system. I cannot run updates anymore.. It goes to 'depmod' then hangs eternally even stopping the system from shutting down.

Here's an example of the 'depmod' or 'modprobe' system hang:

I am stuck, even Kali Linux's instructions don't work:

charles@charles-Inspiron-5482:~/Documents$ sudo apt-get install realtek-rtl88xxau-dkms
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

Per suggestion below: now my 'updates' doesn't get past 'Installing'... my system is broken. I will reinstall Kubuntu later. but I think I'm going to have to return the card.

modprobe rtl8812au didn't work with the card plugged in or not.

It now works as it appears :

charles@charles-Inspiron-5482:~/Documents$ sudo ifconfig wlo1 up

But I've no idea how to make it the OS's default card.

First, fix the "you must manually run 'sudo dpkg --configure -a' to correct the problem.. — waltinator, Feb 18 '20 at 18:55
I fixed it with sudo dpkg --configure -a --force- Now getting this: Reading package lists... Done Building dependency tree
Reading state information... Done E: Unable to locate package realtek-rtl88xxau-dkms — Charles Thompson, Feb 18 '20 at 19:01
Don't add info in comments. Edit (https://askubuntu.com/posts/1211381/edit ) Your post to add info. I've had success with the git branch: git clonehttps://github.com/abperiasamy/rtl8812AU_8821AU_linux.git` — waltinator, Feb 18 '20 at 19:16
it installed correctly and didn't hang at modprobe, but i get kernel module crash in dmesg when I plug the device in, where do I go from here? I think it is still taking off the old one 8812au.ko there is some tainted module there... — Charles Thompson, Feb 18 '20 at 19:20
Remove all dkms drivers that you've installed. Then check the accepted answer at https://askubuntu.com/questions/1185952/need-rtl8814au-driver-for-kernel-5-3-on-ubuntu-19-10. Pay no attention to the filename that says 8812. — heynnema, Feb 18 '20 at 19:28
