How to get rid of wrong kernel (-oracle) from Software Updater update

Software Updater loaded in an -oracle flavour kernel, on which no network works. I've used Grub to set the previous, working kernel as the default.

How do I remove the -oracle kernel, 1a. maybe even get the previous working kernel as a back up so that updater will provide only -generic kernels going forward? I've read How to downgrade kernel after bad update (16.04) and the solution there changed to:

sudo apt remove linux-image-5.15.0-1025-oracle linux-headers-5.15.0-1025-oracle

But it may or may not be the up-to-date answer for this? I'm hesitant to try without wiser heads knowing it is a good step.

Software Updater says everything is up to date. I've reported a bug, no action on the bug report yet. BIOS boots to a NOT EFI, I've tried to force the EFI but it reverts no matter what I try, one time override, disabling those entries, though I have not totally deleted those entries (2 of them are identical an not EFI) running ZFS on the boot drive. hwmatch error showed up after setting the default by setting

GRUB_DEFAULT=saved
GRUB_SAVEDEFAULT=true

and then updating grub. I added the explicit insmod hwmatch Which took care of that error, or at least it is not displayed on boot anymore.

(or am I completely missing something about -oracle or kernels in general? I am just a 'private' afterall.-:)

I have found this reference that explains it is connected to an issue with the nvidia drivers https://ubuntuforums.org/showthread.php?t=2473057

Please [edit your question](https://askubuntu.com/posts/1444546/edit) to add the complete output of `sudo apt update` and the complete output of `dpkg -l | grep oracle`

I have the same issue on ubuntu 23.04. The issue happened yesterday with an update through update-manager. So I complete the previous output:

to be clear, did this do anything other than confirm the oracle kernel(s) are installed?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
