Install the driver of rtl8811-USB-WIFI on ubuntu new machine
1. Update source
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
sudo gedit /etc/apt/sources.list
Copy the following in:

sudo apt install git
git clone https://gitee.com/xxJian/rtl8821CU
sudo apt-get install dkms
cd rtl8821cu
Method 1 is to install through dkms
sudo ./dkms-install.sh
Method 2 is to compile and install
make -j4
sudo make install
I executed both methods, and then I need to restart. After restarting, the network card was found to be normal.
3. Test that
ubuntu18 itself supports multiple wifi network cards.
