I downloaded the drivers on my windows PC and put it on a flash drive. Dragged it to my desktop in Kubuntu (latest version) and tried to install, but can't figure this out. I did chmod +x install.sh and it seemed to work, but when I do ./install.sh the realtek autoinstallation script starts. Looked like there is an error in the script.

This is what I see (I had to copy and paste this to a USB drive to move it to my pc to post this)

What am I missing? I don't have any way to hard wire it, need to get the USB working.

Thanks

This thread from AskUbuntu may help: https://askubuntu.com/questions/1079...ltek-rtl8812bu

I have no way of testing it.

Where was the file downloaded from?
How was it downloaded? (git?, http?, other?)
Exactly what is the file name downloaded?
Where are the instructions for installation?

I could test what you see but need details since it seems there are many sources to obtain the drivers for that card and some links are several years old.

The script is 10 years old, maybe find a more recent version.
And given the typos in the header, and the error you get, I have little trust in the script.

You may just need the firmware package installed, https://howtoinstall.co/en/firmware-realtek

I downloaded it from the manufacturer of the USB wifi dongle. Its called Fenvi, but its not available on Amazon any longer. I got it because its MacOS compatible and this is my MacMini, but its an old MacMini which can't use the latest versions of MacOS. The Dongle is Linux compatible, just have no idea how to compile the driver.

How do I install it without any internet access? I can download it on my PC and put it on USB and just transfer it?

sudo apt-get update
sudo apt-get install firmware-realtek

How do I download it on my PC to transfer it? Once I do copy it over, how do I install it? Just ./firmware-realtek?
I appreciate the help.

I found an old USB wifi that worked with linux perfectly. Its kind of broken, my 2 year old thought ripping the antenna off was a good idea. Was enough to update linux.
