Ubuntu creates cluttered Petitboot menu entries

Status changed to 'Confirmed' because the bug affects multiple users.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general.

You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage. You might also ask for help in the #ubuntu-bugs irc channel on Freenode.

We probably should reduce this (using DISABLE_OS_PROBER), in the cases where we know it's unnecessary, so probably for ppc64el using grub-ieee1275.

Looking at comment 7:
== Comment: #7 - Rolf Brudeseth <email address hidden> - 2015-04-07 18:32:26 ==

Does this mean the issue of cluttered petitboot entries isn't present on 15.04?

[Expired for grub2 (Ubuntu) because there has been no activity for 60 days.]

Problem is still present in 15.04

@mathieu-tl: yes, if we can disable the OS prober when we're installing onto a petitboot-based machine, that'd be great.

Since petitboot will parse the other OS' config files independently, we don't need to include them in Ubuntu's list. Is there a current mechanism to detect the machine type?

Canonical,

Any updates?

This is a patch for grub2 for 16.04 (on top of 2.02~beta2-36ubuntu3.1 which is at xenial-proposed) to add 'GRUB_DISABLE_OS_PROBER=true' on the PowerNV platform of ppc64el.

Let's change target milestone for 16.04.1 (for updates), and this should make daily builds after accepted, and eventually the 16.04.2 ISO.

Hi Canonical,

May you please pick up the attached patch for 16.04 updates?

Thanks!

@taco-screen-team

Can this bug be reassigned to @cyphermox (previously @mathieu-tl), who was working on this before?

Thanks!

I've assigned bug to taco-screen-team. Can someone then assign to cyphermox as I am unable to. Thanks.

That 'target' doesn't seem accurate.
On LTC Bugzilla although the /Version/ field is 14.10, the /Target Milestone/ field is 16.04.x, which seems correct given the reporter's feedback on LTC BZ (internal) comment 47; this is expressed externally on LTC BZ comment 50.

And as far as Canonical status goes, looking at LP, there's no track for 16.04 yet, only 'Ubuntu' which is the current dev version, thus 16.04 at this time, but since the tag ' targetmilestone-inin16041' is set, and the desire for 16.04.x was expressed in comments, that will be taken care of.

Affects Status Importance Assigned to Milestone
? grub2 (Ubuntu) Confirmed Medium ? Mathieu Trudel-Lapierre Edit

So, per that status, still work in progress, cannot close it.

Hope this helps,

Can someone confirm that this fix will be applied to the 16.04.2 ISO?

And on 17.04, if possible!

Thanks,

Targetting to ubuntu-17.01 (end of January) for now so I can see it in the right upcoming work list, this should make sure it doesn't take yet more time to fix.

Could it be applied to 16.04.2 as well since that is an LTS release?

Yes, that's the plan (I'll upload immediately after the upload to 17.04). We're tight on time to make it in to 16.04.2 though.

Hi @sdeziel,

> amd64 user here, this new package asks to remove grub-efi-amd64-signed, is that intended?

No, this change is not related to that,
as seen in this diff between it (2.02~beta2-36ubuntu3.7) and previous version (2.02~beta2-36ubuntu3.6).

Per the version you pasted (1.66.6+2.02~beta2-36ubuntu3.6), I guess that's an effect of a previous change to the grub packages, not applied yet to your system.

Please try to install 2.02~beta2-36ubuntu3.6 (previous version of this change), and see it the same happens.
Per the diff, this change has nothing to do with that behavior.

Thanks!

Disregard this last patch. Problem w/ the bug mirror.

@sdeziel @cyphermox

There's a rebuild of grub2-signed (1.78) associated with this bug.
The proble that @sdeziel reported is related to grub-efi-amd64-signed, so might be related to that part.

Now I see the version installed at @sdeziel system is already 2.02~beta2-36ubuntu3.6, so not sure what's going on.

Might be related to this rebuild.. checking.

Sorry for the noise, the packages arrived at different time on archive.ubuntu.com:

grub-efi-amd64-signed_1.66.7+2.02~beta2-36ubuntu3.7_amd64.deb: 2017-01-13 17:48
grub-efi-amd64_2.02~beta2-36ubuntu3.7_amd64.deb : 2017-01-13 17:14

After updating again, everything looks good and no package is tentatively removed. Thanks Mauricio.

@sdeziel, @cyphermox

No idea what that is due to.

The change in grub2-signed (which didn't seem carried/installed w/ dist-upgrade) is [1] and doesn't introduce a Conflicts: change in debian/control.

Nothing similar with regards to Conflicts: lines are seen in grub2's debian/control either.

Assistance is required to understand that, please.

@sdeziel

Great. Nice catch.

I had missed your last comment.
(and that the version number removed was the old ...3.6 not 3.7.

So, no problems!

Thanks!

This is normal and expected; you need both grub2 and grub2-signed source packages in amd64 and arm64; those have a small delay because grub2 needs to be built (and accepted) before grub2-signed will build.

This is verified OK.

Rolf installed a Power system w/ PowerKVM in one disk, then installed Ubuntu Xenial in another disk, then installed grub2 packages from xenial-proposed.

The comparison of grub.cfg files before/after shows that the entries to boot PowerKVM in the other disk are no longer present (only present in the .orig file, as shown in the diff below).

$ diff /boot/grub/grub.cfg /boot/grub/grub.cfg.orig|grep menuentry
> menuentry 'unknown Linux distribution (on /dev/mapper/ibmpkvm_vg_root-ibmpkvm_lv_system)' --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-7a7bdea5-29ac-4b23-86a6-2cd6f9c510b0' {

It would be great if this went into 16.04.2 since that is an LTS release.

The verification of the Stable Release Update for grub2 has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
