Mate 24.04 with Kernel 6.11

Support & Help Requests

1

Last year I installed Mate 24.04 on my desktop and laptop pcs, kernel was 6.8.
Last may I had to reinstall my desktop pc due to a SSD crash, this time I installed 24.04.2 and it went with kernel 6.11.
I wonder if there is a way to upgrade my laptop installation to 24.04.2, because the update manager doesn't propose the upgrade.
Obviously I don't wish to reinstall.
thx.

I'm not sure what you're actually asking...

Ubuntu flavors LTS release ISOs with both the GA and HWE kernel stacks.

  • Ubuntu MATE 24.04 & 24.04.1 ISOs used the GA (6.8) kernel stack; the kernel package installed is linux-generic, so installs of that remain using the 6.8 kernel
  • Ubuntu MATE 24.04.2 LTS uses the HWE kernel stack which is 6.11 at .2; kernel package installed is linux-generic-hwe-24.04
  • Ubuntu MATE 24.04.3 LTS (still in QA) again uses HWE which is now 6.14; later point releases of 24.04 will use HWE updated from a backported kernel release until 24.04.5 which uses the GA stack from 26.04; kernel package still linux-generic-hwe-24.04 which changes over time.

A scan of current kernels for 24.04 show (quick CLI command output paste)

The noble shows what was on the initial 24.04 release for given architectures; and noble-updates / noble-security etc what you'd expect if updates are applied (or used the latest noble daily which will be released as 24.04.3 soonish)

This may not be what you're asking, but sorry I'm not sure what that is... My point is Ubuntu MATE have released media which will remain on 6.8 kernel, PLUS media which advances and using the HWE kernel stack..

If you want to understand more about GA/HWE (not so much OEM) kernel stacks, refer wiki.ubuntu.com/Kernel/LTSEnablementStack where Ubuntu MATE and all flavors still do as Ubuntu Desktop 18.04 LTS & earlier did.

Use these commands to update and upgrade to 24.04.2, with small repair if needed, then to use the latest kernel 6.14 with Ubuntu HWE.

sudo apt update
sudo dpkg --configure -a
sudo apt-get install -fy
sudo apt-get autoclean
sudo apt-get autoremove --purge -y
sudo apt full-upgrade -y
sudo apt install linux-image-generic-hwe-24.04
