[ SOLVED ] Kernel Install/Remove issue with a kernel later than what LL provides

[humdinger70]

Well, other than a little unsureness with GRUB, I managed to remove the 4.11 kernel and go back to 4.4.0-79.

Also, the kernel removal tool only sees the kernels that LL knows about. Removing the 4.11 kernel is not provided as an option.

Can this be fixed? If I wanted to remove the 4.11 kernel and go back to the 4.4 series as default, what needs to be done?

You cannot remove the kernel you're currently booted to, if you reboot choosing advanced on grub and choose boot to 4.4.x, then will you be able to remove 4.11...
Only remove a previous once you're sure the new is working satisfactorily...


OOPS sorry Jerry covered this..

I'm seeing updates to the 4.4 kernel family, but nothing for the 4.11 family

You won't see updates for our custom kernels. They are made available to people who need them (incompatible hardware)

Also, the kernel removal tool only sees the kernels that LL knows about. Removing the 4.11 kernel is not provided as an option.

You need to boot into the old kernel in order to see the new one in the removal list.

You need to boot into the 4.4 kernel to remove the 4.11. Please only install kernels if you truly need them. Curiosity can end you up in chaos sometimes

The default kernel in LL 3.4 is the 4.4 family. Just for the heck of it, I installed a much later kernel (4.11.0) and it's my default boot kernel. It works fine so far.


Issue comes with updates - I'm seeing updates to the 4.4 kernel family, but nothing for the 4.11 family (and there have been updates to it, per the news page at lwn.net). Also, the kernel removal tool only sees the kernels that LL knows about. Removing the 4.11 kernel is not provided as an option.
