Recently I have added some new devices to my homelab, phone size machine with Intel N5105 CPU, 16GB RAM and 256GB SSD storage, wanted to build a kubernetes cluster use 4 such machines. It also has built-in 2.5G NIC, WIFI6 and Bluetooth version 5.2, but the current Ubuntu LTS(20.04) has linux kernel 5.4 which don’t support the NIC driver, need to upgrade kernel to solve this.

Test amd64/build succeeded (rc=0, on=amd64, time=0:11:17, log=amd64/log)

Download all the deb files and save to a USB drive(FAT format), insert to the device and mount,
lsblk # to check the USB label
sudo mkdir -p /mnt/usb
sudo mount /dev/sdb2 /mnt/usb
# Install all the kernel packages
cd /mnt/usb
sudo dpkg -i *deb
Assign static IP address to file /etc/netplan/00-installer-config.yaml
