First: I changed the Category from Feedback to General Help because this is more a Help Request.
To Your Issue:
The oem Kernel is not the Standard Kernel. Did You installed that manually? Could You post the complete Content of the GRUB config File /etc/default/grub please? So, we can have a complete Overview from it.
Thank you for your replay.
I do not really remeber to have installed it on pourpose. So it's a bit strange it is in use.
/etc/default/grub:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_CMDLINE_LINUX=""

Answer Brave AI (Leo):
The setting GRUB_FLAVOUR_ORDER=oem is a hidden configuration option in the Ubuntu grub2 package that allows users to specify a preferred kernel flavor for the default boot entry.
You set at the Beginning of the Line a # to comment it out so it looks like this:
#GRUB_FLAVOUR_ORDER=oem
Then make a sudo update-grub and check if it starts in the 7.0 Kernel. If it shouldn't directly start in the 7.0 Kernel, choose on the GRUB Menu one time the 7.0 Kernel in ''Advances Options'' and then check if it stays with rebooting again.
For clarity: What this does is lock you into the 7.0 kernel you are currently on. So when it gets an update, you will keep booting into this kernel, not that new one.
The cause of the original issue was that you were not using the HWE line, but using the OEM kernel, instead. Since there was no update to the OEM, you remained on the only available OEM kernel.
Removing the OEM and then installing the HWE would put you on track to then upgrade to the 7.0 HWE kernel.
However
I do not recommend doing this just to see a higher kernel number. There is a reason you were on the OEM kernel and since I do not know at this distance what that reason is... it cannot be said you should switch kernels.
Thank you for your replay.
I understand your point. At the moment I'm using the 7.0 kernel and I do not have any problem. I will keep testing and in case switch back to the oem ones.
