Expected

Expecting an updated menu entry to boot into after an update.

Actual Behavior

Update doesn't get added to grub menu and stays stuck on 38.20231012.0

Steps to reproduce it

  1. rpm-ostree upgrade
  2. systemctl reboot

Provide any additional data that may help debug this - which specific version of
an RPM is in the repo, or any host system configuration.

Please let me know what else is needed to add to help debug this. I have no layered packages installed. All the apps I have installed are flatpaks.

Would you like to work on the issue?

I won't be able to fix this myself as I don't have the skills. Would need help with this bug on my particular system.

Can you check the output of journalctl -u ostree-finalize-staged?

Looks like I am hitting this too on 2023.11

Looks like this might be a bit different from #3715 as the error I get from Grub seems different. I also tried the two workaround listed in that issue, with no luck.

Do you actually need dual-booting? If not, you can stop using grub2-mkconfig entirely by switching to sysroot.bootloader=none but you need to make sure you have a new enough GRUB first (see fedora-silverblue/issue-tracker#120). If you're not sure, a safer option that should work is a dropin to ostree-finalize-staged.service that sets Environment=GRUB_DISABLE_OS_PROBER=true.

@jlebon when you say dual-booting you mean two different OSes? I just use grub to select the different ostree deployments. I just installed silverblue on this new laptop a few weeks back. If you mean it thinks It needs to support multiple OSes I wonder what I did different vs my previous machine.

/usr/sbin/grub2-probe: error: failed to get canonical path of `overlay'.
error: Bootloader write config: grub2-mkconfig: Child process exited with code 1

This is triggered by combination of composefs (which uses overlayfs) and the legacy case of not having sysroot.bootloader=none. os-prober is getting confused by the composefs (really overlayfs).

WARNING: These instructions may cause failure
If you have a new enough GRUB (and anyone having done a fresh Fedora install since at least F37 does) then you can:

sudo ostree config set sysroot.bootloader none

Now, this issue is quite similar to coreos/coreos-installer#1203 - we may need to teach os-prober to do the same. (See also containers/composefs#144 )

This left me without being able to boot and with a grub prompt. I will try to replicate the issue in a VM once I finish getting my machine running again. Given that I had enabled composefs I wonder if this is related at all from what the OP was experiencing.

It's definitely a different triggering cause yeah. I hid the instructions above for now.

I tried composefs due to https://blogs.gnome.org/alexl/2024/01/15/testing-composefs-in-silverblue/ and got similar results.

Initially I wasn't able to create new deployments and it also apparently prevented me from getting new commits at all until I rebased.

I also managed to bork GRUB and has to boot on a live session to tell it to regenerate the grub config.

I find that it is not relevant to os-prober and setting GRUB_DISABLE_OS_PROBER=true will not work. It is caused by line 142 of /usr/sbin/grub2-mkconfig:

# Device containing our userland.  Typically used for root= parameter.
GRUB_DEVICE="`${grub_probe} --target=device /`"
GRUB_DEVICE_UUID="`${grub_probe} --device ${GRUB_DEVICE} --target=fs_uuid 2> /dev/null`" || true
GRUB_DEVICE_PARTUUID="`${grub_probe} --device ${GRUB_DEVICE} --target=partuuid 2> /dev/null`" || true

Closing this as a dup of ostreedev/ostree#3198

@cgwalters cgwalters closed this as not planned Won't fix, can't repro, duplicate, stale Aug 29, 2024
