Got a 'new distribution available' upgrade message today on my Ubuntu Linux family/work computer (it was 18.10 Cosmic Cuttlefish and wants to go to 19.04 Disco Dingo), so of I course decided to update right away. Clicked OK and let it do it's thing .. it did take some time to download (presume everyone is updating today as well), but after a Sat afternoon nap and responding to a few config questions and a longer nap came back and found it all updated for me. The only thing not working right off was my usb wifi adaptor. It is a Startech Mini-Wireless N I had floating around. It is based on a Realtek RTL8811au chip. Google tells me that particular chip has no drivers online but that the RTL8812au does and should be compatible. To install it, had to first plug the wired network cable back in and run these commands in terminal:
sudo apt install git dkms build-essential
git clone https://github.com/abperiasamy/rtl8812AU_8821AU_linux.git
cd rtl8812AU_8821AU_linux
sudo make -f Makefile.dkms install
which worked fine .. the make script installed the newest version available and compiled it for the new 19.04 (Apr 2019 Disco Dingo) distribution. Apparently the command below would have worked also:
sudo apt install rtl8812au-dkms
Everything else seems to be where it should be .. it even retained my desktop configuration settings. Nice!
