I am trying to install Debian 9.80, but when I am asked for which package manager I would like to use, I choose default options, but I can't go on without an internet connection. I skipped past it, but I can't find a way to install packages without going through a million dependencies using the https://www.debian.org/distrib/packages. My adapter is a BrosTrend AC1200 AC3 Wifi Adapter. I gotten it to work on Ubuntu using https://blog.danielscrivano.com/installing-rtl8812au-on-linux-for-wireless-dual-band-usb-adapters/ but I want to get it working on Debian.
1Hello and welcome to SE. Why don't you use the link you provided to compile the driver for your Debian?– PankiMar 19, 2019 at 9:48
Because the installation is done without an Internet connection
apt will not be configured correctly.
1) Edit your
sudo nano /etc/apt/sources.list
with the following lines:
deb http://deb.debian.org/debian stretch main deb-src http://deb.debian.org/debian stretch main deb http://deb.debian.org/debian-security/ stretch/updates main deb-src http://deb.debian.org/debian-security/ stretch/updates main deb http://deb.debian.org/debian stretch-updates main deb-src http://deb.debian.org/debian stretch-updates main
sudo apt update sudo apt upgrade sudo reboot
2) Installing the Realtek driver following the steps described on the blog posted in your question (
linux-headers-generic isn't available for debian it will be replaced by
sudo apt-get install linux-headers-$(uname -r) build-essential git git clone https://github.com/scrivy/rtl8812AU_8821AU_linux.git cd rtl8812AU_8821AU_linux make sudo make install sudo modprobe rtl8812au
