Kernel version is still 4.15, after upgrading to 5.1 Hera

Question

I've updated my system, but it didn't update the kernel. Please see the output of my commands:

loathe@elementaryos ~> lsb_release --all 
No LSB modules are available.
Distributor ID: elementary
Description:    elementary OS 5.1 Hera
Release:    5.1
Codename:   hera
loathe@elementaryos ~> uname -r
4.15.0-72-generic

After running "apt update", it says my packages are up to date. How can I update the kernel, and any other packages if they should be updated too(didn't check other packages besides the kernel)?

Answer 1

According to the announcement blog post:

…if you’re on an existing Juno install and would like or need the improved hardware support, you can install it from Terminal with the following command:

sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

Answer 2

For Elementary OS 5.1 you need to update your kernel like this

Check your kernel version

$ uname -r                                                                            
4.15.0-72-generic

Update your kernel

$ sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
