dnf log

Description of problem:
System upgrade fails. /var/log/dnf.log (attached) shows the following towards the end (I guess this is the critical section):

Version-Release number of selected component (if applicable):
dnf-plugin-system-upgrade-0.4.1-1.fc22.noarch
dnf-1.1.1-2.fc22.noarch
systemd-219-24.fc22.x86_64

How reproducible:
I tried it twice and it happened both times.

Steps to Reproduce:
1. Follow guide at https://fedoraproject.org/wiki/DNF_system_upgrade
2. Run `sudo dnf system-upgrade download --releasever=23 --distro-sync --best`
3. Run `sudo dnf system-upgrade reboot`

Actual results:
System gets upgraded to F23

Expected results:
After a short period where I expect the system to be performing the offline upgrade, the system reboots back into F22 (it's too quick for me to see what gets printed to the console when it fails to upgrade).

Additional info:
Comment 1 Will Woods 2015-09-25 20:15:06 UTC 
Ah - this is probably because the '--best' flag isn't carried over into the upgrade, so the depsolving is slightly different and it fails even though the transaction test at the end of the "download" succeeded.

If you add "--best" to the dnf command in /lib/systemd/system/dnf-system-upgrade.service, the upgrade will probably work.

If so, (or if not!) can you attach /var/log/dnf.log and the output of
"journalctl -b -1" after the upgrade?
Comment 2 Will Woods 2015-09-25 22:00:54 UTC 
If I'm right about the cause of the problem, then this should be fixed by commit 49a9318:

dnf log after adding --best to config

Hi Will,

Thanks for getting back to me so quickly.

I've done this now so that the command reads:

> /usr/bin/dnf --releasever=${RELEASEVER} --best system-upgrade upgrade

After updating the command, I ran the download step again, and then the reboot. There was a similar failure, but just on other packages.

Attached. After capturing the attached logs, I removed fluidsynth-libs and retried, but it just failed at one of the other packages in that list.

Is this included in any build somewhere that you'd like me to try?

So here's the error, for the record:

It's troubling that

  dnf system-upgrade download --releasever=23 --distro-sync --best

*didn't* trigger this error, but

  dnf --releasever=23 --best system-upgrade upgrade

*did* trigger it. (Don't worry about --distro-sync there; that gets pulled from /var/lib/dnf/system-upgrade.state)

In theory, those commands should construct the same transaction from the same metadata, which means either they should both succeed or both fail. Other than not automatically carrying "--best" over like we do with "--distro-sync", I'm not sure what else might be different to make the transactions run differently.

So it looks like passing "--best" isn't enough to make this work. Which means the patch I mentioned above probably wouldn't fix the problem anyway. Alas.

Could you maybe try running the "download" command with "--debugsolver" added, and then attach the resulting "./debugdata" directory? That might give me some idea of where to start..

Hi Will,

Let me know if you want me to provide anything else or try anything else.

Gerard.
Comment 7 Gerard Ryan 2015-10-02 18:39:24 UTC 
There's an info message in the dnf.log when the error occurs, saying: "try to add '--allowerasing' to command line to replace conflicting packages". Should I be doing that?

Also, when I do the reboot, it boots with an f22 kernel for the update part. Is that correct, or should that be an f23 kernel? IIRC, fedup used to boot into the new one, right?

Yes. You should probably remove --best, and do --distro-sync --allowerasing.
This will be the default behavior in the next version of the plugin.

(Be sure to check the transaction to make sure it's not removing anything you really need. If it is, you might want to until those packages get their deps fixed to upgrade your system.)

Correct, dnf system-upgrade doesn't do that. No special kernel is needed. Just "dnf system-upgrade reboot" and let your system boot. (It'll run the upgrade no matter which kernel you pick.)

Does using "--distro-sync --allowerasing" let the upgrade work?
Comment 9 Gerard Ryan 2015-10-02 19:28:58 UTC 
(In reply to Will Woods from comment #8)
> Does using "--distro-sync --allowerasing" let the upgrade work?

I've just tried that now:

> sudo dnf system-upgrade download --releasever=23 --distro-sync --allowerasing

but it failed early with:

> Last metadata expiration check performed 1:19:44 ago on Fri Oct  2 19:06:00 2015.
> Dependencies resolved.
> Error: The operation would result in removing the booted kernel: kernel-core-4.1.7-200.fc22.x86_64.

This is the case even when I remove the '--best' flag from /lib/systemd/system/dnf-system-upgrade.service as suggested in comment #1.
Comment 10 Zbigniew Jędrzejewski-Szmek 2015-10-05 16:01:08 UTC 
Yeah, I can reproduce this with system_upgrade.py from git (I get the same error about the kernel). To debug further, I included --debugsolver in both 'download' and 'upgrade' commands. solver.result from the upgrade contains @commandline everywhere, so I did sed 's/@commandline/fedora/g' debugdata/solver.result > solver.result.sedded. There's quite a difference:

In 'download', the transaction removes a bunch of packages, even though --allowerasing was not used. But then in the real transaction this doens't happen, and the upgrade fails. So maybe the problem is in the download transaction, which behaves as if --allowerasing was used.

That hypothesis was wrong. What happens is that packages which were queued for removal during download, are not properly marked for removal during the upgrade.
Comment 13 Will Woods 2015-10-09 18:39:39 UTC 
If I understand correctly, the debug output in comment #10 and comment #11 shows that the transaction is resolved differently between 'download' and 'upgrade' even *without* using --best or --allowerasing.

Which means that if we want the upgrade transaction to work reliably, we need:

a) short term: some help from the DNF team to figure out what causes the difference in depsolving (different config parameters? metadata expiry? something about the way I'm adding the downloaded packages to the sack?)

b) long term: a DNF-approved method to save/load transactions. Or at least documentation on what's required to regenerate the same transaction during the upgrade.

I'm adding jsilhan, who I'm hoping might be able to help us figure out where to go from here - or at least who else to ask.

(In reply to Will Woods from comment #13)

Yes, on all counts.
Comment 15 Adam Williamson 2015-10-20 00:31:31 UTC 
wwoods has indicated he considers this pretty critical for F23 upgrades, so proposing as a blocker:

https://bugzilla.redhat.com/show_bug.cgi?id=1263677#c26

obviously this is a conditional violation of "For each one of the release-blocking package sets, it must be possible to successfully complete an upgrade from a fully updated installation of the previous stable Fedora release with that package set installed." (Beta), the condition being "you hit whatever conditions trigger this mismatch".
Comment 16 Stephen Gallagher 2015-10-20 00:39:56 UTC 
This seems like a really crummy bug, but I'm not certain it's necessarily a blocker for upgrades, considering that it requires the specification of the non-default --best flag. I think this is a candidate for a Common Bug (beware, here be dragons, etc.) and a Freeze Exception if this gets fixed in time.

I'm 0 on blocker from the current information, but +1 FE.
Comment 17 Adam Williamson 2015-10-20 00:49:56 UTC 
"If I understand correctly, the debug output in comment #10 and comment #11 shows that the transaction is resolved differently between 'download' and 'upgrade' even *without* using --best or --allowerasing." (from #c13)
Comment 18 Mike Ruckman 2015-10-20 00:57:52 UTC 
If I'm reading this report correctly, it even fails w/o the "--best" flag - in fact, it fails with several different permutations. I'm leaning +1 just because upgrades should work, and I'd want to make sure we address any bugs that could impact that.

+1 Blocker.
Comment 19 Kevin Fenzi 2015-10-20 01:28:11 UTC 
So, this is the f22 dnf and dnf-system-upgrade? or the f22 dnf at 'download' and f23 dnf at 'upgrade'?

Guys, it's highly likely this is just another manifestation of bug 1260989. Has somebody reproduced these issues after installing this update https://bodhi.fedoraproject.org/updates/FEDORA-2015-02efefba0e ?

I'll install those updates this evening & try & report back.

I got the bug a couple of days ago:

dnf system-upgrade reboot

This has solved the issue for me & I'm now happy to be reporting from f23. Thanks a lot! :)
Comment 24 Zbigniew Jędrzejewski-Szmek 2015-10-21 04:51:10 UTC 
I can confirm that. With https://bodhi.fedoraproject.org/updates/FEDORA-2015-02efefba0e things seem to work fine.
Comment 25 Andreas Tunek 2015-10-21 19:09:39 UTC 
Works for me as well (when I actually updated libsolv, a bit hard to see...).
Comment 26 Kamil Páral 2015-10-22 07:51:46 UTC 
Thanks for testing, marking as a duplicate.
