Downgrading Kernel

I have been searching around the forum and I failed to sort this out.

I am experiencing freezes multiple times a day and I know that with a previous install of 4.2 and kernel 6.3.9-1.qubes.fc37.x86_64 my laptop was running smoothly. Then I had to reinstall and I am on kernel 6.5.8-1.

How can I downgrade and install 6.3.9-1?

I have tried qubes-dom0-update kernel*** and I get no match for argument error.

I also downloaded for desperation the rpm file from the repository and installing it with dnf I ger error: Problem conflicting requests.

Please help me out.

Kernel version 6.3.9 is part of the kernel-latest package. If you want this specific version, then you need to run this command in dom0:

sudo qubes-dom0-update kernel-latest-6.3.9-1.qubes.fc37 kernel-latest-qubes-vm-6.3.9-1.qubes.fc37

Wonderful it worked. Thanks
