Upgrade Ubuntu kernel

· One min read

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.

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.17/

Test amd64/build succeeded (rc=0, on=amd64, time=0:11:17, log=amd64/log)
amd64/linux-headers-5.17.0-051700-generic_5.17.0-051700.202203202130_amd64.deb
amd64/linux-headers-5.17.0-051700_5.17.0-051700.202203202130_all.deb
amd64/linux-image-unsigned-5.17.0-051700-generic_5.17.0-051700.202203202130_amd64.deb
amd64/linux-modules-5.17.0-051700-generic_5.17.0-051700.202203202130_amd64.deb

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

network:
version: 2
renderer: networkd
ethernets:
enp1s0:
dhcp4: no
addresses: [192.168.3.12/24]
routes:
- to: default
via: 192.168.3.1
nameservers:
addresses: [114.114.114.114, 114.114.115.115]

After those change, do a reboot. And upgrade all the package with

sudo apt update
sudo apt --fix-broken install -y
sudo apt upgrade -y
sudo apt autoremove
