I'm installing Ubuntu 18.04. It was very smooth and fast to install it as a dual boot system with Windows 10 already there. It hardly took any of my time and it must have only run for 15 minutes. But... WiFi isn't working. It's a Realtek RTL8822BE network adapter, so it's supposed to work with version 4.14 of the kernel and I have 4.15: https://www.phoronix.com/scan.php?page=news_item&px=Linux-Realtek-RTL8822BE But it looks like I need certain programs to install a driver, and those programs were not included with the base system. For example, this bit of codee uses dkms... git clone -b extended https://github.com/lwfinger/rtlwifi_new.git sudo dkms add ./rtlwifi_new sudo dkms install rtlwifi-new/0.6 sudo cp /usr/src/rtlwifi-new-0.6/firmware/rtlwifi/* /lib/firmware/rtlwifi/ ...and this uses make: git clone https://github.com/synthtc/rtlwifi-next cd rtlwifi-next sudo make install sudo modprobe -r rtl8822be # make sure secure boot is turned off or the next line will fail sudo modprobe rtl8822be But I don't have either dkms or make installed and they have a bunch of dependencies: $ sudo apt show dkms Package: dkms Version: 2.3-3ubuntu9.2 Priority: optional Section: admin Origin: Ubuntu Maintainer: Ubuntu Developers <ubuntu-devel-discuss at lists.ubuntu.com> Original-Maintainer: Dynamic Kernel Modules Support Team <pkg-dkms-maint at lists.alioth.debian.org> Bugs: https://bugs.launchpad.net/ubuntu/+filebug Installed-Size: 290 kB Depends: kmod | kldutils, gcc, dpkg-dev, make | build-essential, coreutils (>= 7.4), patch [snip] So ... what's the trick? I have the bootable USB stick I used to install Ubuntu and it has plenty of room on it. Is there an easy way to download all the packages to that USB stick? (Could boot it on another laptop where networking works.) I could then copy the package files to the laptop, and there must be another easy command I could use there, right? It seems like there should be a fairly automatic way of doing it. TIA. Best, Mike
