Cannot Install Kernel-latest in Dom0

User Support General
1

I am running qubes R4.2.3

When I run:

sudo qubes-dom0-update kernel-latest

I get the following error:
“No Match for argument: kernel-latest”

But looking at the output, I do see it actually download kernel-latest and kernel-latest-modules.

Am I doing something wrong? I searched the forum and did not find something similar, but maybe I missed something.

You might need to enable the testing repos in dom0. There’s an option in the Qubes Global Config GUI, or if you’re a terminal person, try this:

sudo qubes-dom0-update --enablerepo=qubes-dom0-current-testing kernel-latest kernel-latest-qubes-vm

I did try the testing repo as well, but that gave the same result. Could not find kenel-latest.

I’m attempting to recreate now, but I can’t seem to get the same result as you.

I do know that when I changed my AppVMs over to Fedora 41 templates, I had to run dnf clean all otherwise it would refuse to download anything, throwing errors while trying to reconcile partial downloads with identical file names from different repos (drove me crazy for days, couldn’t figure out why…).

Maybe try the command with the --clean option?

sudo qubes-dom0-update --clean --enablerepo=qubes-dom0-current-testing kernel-latest kernel-latest-qubes-vm

If that doesn’t work, I noticed this:

Is your system clock accurate (or close enough)?

That was something I did not check was the time. I did

sudo qvm-sync-clock

And verified the time was correct, and it is (6:28 EST)

I ran the command you pasted (I did --clean previously but never all in one)
but got the same result (and the -1 day metadata) which I agree is curious. Maybe I did something while the clock was not right and its been messed up since?

I ran --action=“makecache”, then re-ran the above commands and it no longer says check: -1 day. however the problem still persists, the end result was the same

I installed the latest updates and it is working fine now. No idea as to the cause. Thanks for the helping though!
