i have an new Ubuntu 20.04.3 Desktop installation and i want to switch from the default HWE kernel to the GA kernel. I had aleready installed the GA kernel and the symlinks inside the boot folder are pointing to the correct 5.4 (GA) kernel.

I tried to execute.

update-grub

But Grub is still loading the 5.13 kernel per default and is not listing the 5.4 kernel but the deinstalled 5.11 kernel.

Grub --> advanced

Any ideas how to solve this issue? Best regards!

Did you read the documentation; ie. https://wiki.ubuntu.com/Kernel/LTSEnablementStack as I find the "*To downgrade from HWE/OEM to GA kernel:*" rather clear... Did you follow the steps? It's optional to remove the HWE stack (ie. you'll get both offered until it's removed) so how far did you get?

Hello, yes of course. but i can't remove the kernel 5.13 because it is booted. if i uninstall anyway grub can't find the kernel and i can't boot. Basically i need to force grub to boot the 5.4 kernel but there´s no option for that.

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.
