Similar problem has been detected:

1. Try to install flatpak package from flathub using gnome-software or 'flatpak install' from command line.
2. Segfault occurs at libcurl in the middle of package download.

Comment 16 Jonathan Lebon 2019-05-03 14:05:54 UTC 
Not sure what's going on there. I've only looked into this superficially. Opened up an issue upstream to raise visibility: https://github.com/ostreedev/ostree/issues/1848.
Comment 17 Link Dupont 2019-05-03 16:58:42 UTC 
I explored this a bit last night and found the following. I hope this helps. I'm happy to run
some more experiments too.

* On my desktop running Fedora 30, flatpak segfaults. In a VM running Fedora 30 on the same host,
  flatpak *does not* segfault.
* On the same desktop running the Fedora 30 Live ISO, flatpak segfaults.
* On my laptop running Fedora 29, flatpak does not segfault. In a VM running Fedora 30 on the same
  Fedora 29 host, flatpak *does not* segfault.
* When I boot my laptop with the Fedora 30 Live ISO, flatpak segfaults.
Comment 18 Jonathan Lebon 2019-05-03 17:44:18 UTC 
Are the segfaults consistent? If so, could you add `http2=false` to the flatpak remote in question (e.g. `/var/lib/flatpak/repo/config` for system flatpaks) and try again?

I added http2=false to the [remote "flathub"] section. And it still segfaults at about 13%.
Comment 20 Link Dupont 2019-05-04 17:11:09 UTC 
I disabled the IPv6 WAN interface on my router and (without the http2=false addition to /var/lib/flatpak/repo/config) flatpak is no longer segfaulting.
Comment 21 Matías Zúñiga 2019-05-13 17:32:39 UTC 
I have the same problem with a fresh fedora 30 install and flathub, disabling IPv6 fixes the segfaulting for me

Comment 23 Jonathan Lebon 2019-05-27 13:17:18 UTC 
From https://bugzilla.redhat.com/show_bug.cgi?id=1713888, I'm going to move this to ostree for now (though the IPv6 workaround tells me this is likely a libcurl issue).

Just as another test point, does the workaround in https://bugzilla.redhat.com/show_bug.cgi?id=1697566#c21 also work for you?
Comment 26 Chris Murphy 2019-06-24 14:57:35 UTC 
As it turns out this is somewhat transient, occurring maybe 50% of the time or less, and only on large runtimes like freedesktop. It's never happened once with an application stack.

Is it sufficient to go to the Wifi connection, click on IPv6, and set IPv6 Method to Disable? Or something else?
Comment 27 Chris Murphy 2019-06-24 16:21:00 UTC 
On Rawhide, I've only gotten the crash twice out of maybe a dozen attempts, but I got this three times...

Comment 28 Yağmur Oymak 2019-06-30 14:56:29 UTC 
The cause is probably this: https://github.com/curl/curl/issues/3952

Looks like it's fixed in libcurl 7.65.

Also see: https://github.com/flatpak/flatpak/issues/2977
Comment 29 Chris Murphy 2019-06-30 15:56:02 UTC 
The same problem causes gnome-software to crash, but it's actually libcurl according to the developers in the upstream flatpak issue. I posted to the libcurl list and they think it's probably fixed already in master. I'm going to switch the component to curl, see if a straight update from 7.64-7 to 7.65-1 is sane, or if a backport is possible.
Comment 30 Kamil Dudka 2019-07-01 07:26:37 UTC 
Thanks for the report!  I will backport the upstream fix.

At least one user confirmed that the update helped.  So either you are facing an unrelated issue, or the fix was incomplete.  In any case, please file a separate bug report with up2date backtrace etc.

crash stack from abrt with curl 7.64.0-8.fc30

I'm on curl 7.64.0-8.fc30 but still got a crash inside libcurl in one occasion.  Attaching stack from abrt.
Comment 38 Mark Pariente 2019-07-11 05:14:43 UTC 
The issue still persists for me on curl-7.64.0-8.fc30.x86_64. On one of my machines flatpak update / flatpak install results in 100% segmentation fault. According to https://github.com/flatpak/flatpak/issues/2977 the curl issue is fixed in version 7.65.1 - so we'd need that version in fedora 30.
Comment 39 Mark Pariente 2019-07-11 19:06:38 UTC 
I get the same crash with curl-7.65.1-1.fc31.x86_64 from rawhide as well. According to https://github.com/flatpak/flatpak/issues/2977 the fix might be in curl master and not yet released.
Comment 40 Mark Pariente 2019-07-11 23:07:13 UTC 
I can confirm that curl master (7.65.2-DEV) fixes the issue for me. I'm providing the steps that I used to try that out in case it's helpful to others:

git clone https://github.com/curl/curl.git
cd curl
./buildconf
./configure --with-gnutls
make
LD_LIBRARY_PATH=$PWD/lib/.libs flatpak <whatever flatpak sub-command that used to crash before>

(you also need to dnf install gnutls-devel if it's not already installed on your machine - might need to install more development related packages also).
Comment 41 Chris Murphy 2019-07-12 01:03:23 UTC 
I'm lost in the details. What I know is a clean installation of Fedora 30 fully updated, cannot install any flatpak I've tried, and flatpak folks have said it's a libcurl problem best they can tell; and yet supposedly that fix was backported to 7.64.0-8. So if that's not the fix, what in master/7.65.2 did fix it and can that be backported? Or is there a process to rebase Fedora 29 and 30 to upstream as long as there isn't an SONAME bump?
Comment 42 Chris Murphy 2019-07-12 01:16:59 UTC 
Mark, if you revert your changes back to a condition where you can reproduce the failure; what happens if you disable IPv6 as suggested in comment 20? I tried setting IPv6 to Disabled in GNOME Settings, and 1 crash for 1 attempt. So I'm not sure that's the problem, but I'm having some transience in reproducing this anyway (way easier to reproduce in Fedora 30 than Rawhide, with the same kernel).
Comment 43 Mark Pariente 2019-07-12 01:42:33 UTC 
Wow, very interesting. I disabled IPv6 by adding ipv6.disable=1 to the kernel boot cmdline in grub and it *did* fix the issue for me. Without this I have 100% segfault rate with 'flatpak update'. Trying to disable IPv6 via GNOME network settings didn't work (flatpak still segfaults), but the kernel cmdline boot option did the trick.

Where earlier this week that message was that the server reported error 502. So for me the failure blame are transient.

However, if I boot with ipv6.disable=1 I'm able to successfully get multiple installations to complete. That's the first time I've gotten a successful flatpak installation on this particular system.

Actually, the bug is so severe that after activating the flathub repo, gnome-software starts to crash too.

Process 3532 (gnome-software) of user 1000 dumped core.

Comment 48 Parag Nemade 2019-07-14 16:46:40 UTC 
I even lost rpm-ostree upgrade functionality on F30 but this can be different issue. Also, flatpak is randomly segfaulting. You need to keep attempting again and again till it works.

systemd-coredump[19226]: Process 2211 (rpm-ostree) of user 0 dumped core.

Could everyone running into this try (temporarily) booting with ipv6.disable=1 boot parameter, and then retest?

Could you please provide some steps to reproduce it (ideally a finite sequence of commands one can execute to trigger the crash locally)?

I am not a user of flatpak/gnome myself...

1 - Activate the use of the flathub repo (open https://flathub.org/repo/flathub.flatpakrepo )
2 - Install any package: flatpak install flathub org.telegram.desktop --verbose

4 - With flatpak active gnome-software starts to crash too because they are integrated:

Open with what?  Which command should I type?

You just have to open the link with your browser and gnome-software will install the repo. You don't have to be root.
Here is the command line:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

I tried to open the link with elinks but it just displayed some text.

> You don't have to be root.

If I run the commands as non-root, it asks me for password all the time.

Thanks!  This time it did something but it did not crash:

[kdudka@f30 ~]$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Comment 56 Parag Nemade 2019-07-16 12:03:59 UTC 
somehow I removed layered packages in my F30 Silverblue system and able to do "rpm-ostree upgrade" to recent available update.
Today, I was trying to run this command
$ flatpak install org.gnome.eog

This keep failing for me with segfault. On 3rd attempt it worked and I can use eog flatpak now.
Then I checked journalctl for relevant log and found

It works fine on my VM with curl-7.64.0-8.fc30.x86_64:

Could anyone from the flatpak/gnome team create an isolated reproducer on top of libcurl?
Comment 58 Henrique C. S. Junior 2019-07-16 15:19:14 UTC 
It is weird, but I've noticed a pattern here. In my super-fast optic fiber connection at work flatpak works like a charm, but at home, with a normal 15 MB DSL it crashes 98% of the time.
Comment 59 Kamil Dudka 2019-07-17 11:15:06 UTC 
Could you please check whether curl-7.65.2-1.fc31 works any better?

Thanks for checking but you tested it with curl-7.65.1-1.fc31 whereas I had suggested to test curl-7.65.2-1.fc31.
Comment 62 Henrique C. S. Junior 2019-07-17 13:33:49 UTC 
I'm unable to find the .2 version (even with --releasever=rawhide):

sudo dnf install curl-7.65.2-1.fc31.x86_64 --releasever=31 --enablerepo=*testing --disablerepo=*modular
Last metadata expiration check: 0:09:39 ago on Wed 17 Jul 2019 10:21:17 AM -03.
No match for argument: curl-7.65.2-1.fc31.x86_64
Error: Unable to find a match

Can you share a .srpm?

(By the way, I'm on F30 yet, so I have to change releases using DNF).

It might have not reached your mirror but the build exists in Koji:

I could create copr for testing in case it helped.

I can rebuild your srpm, no problem, but maybe the Copr can help more people test too.
Comment 65 Kamil Dudka 2019-07-17 15:25:55 UTC 
OK, I created a copr for testing:

Looks like you nailed it!
I have tried installing and updating soma packages and it worked.
Thanks for going the extra mile.

Comment 67 Kamil Dudka 2019-07-17 16:53:05 UTC 
Thank you for testing it!  If we do not have a reliable self-contained reproducer, I guess it will be easier to just rebase curl to curl-7.65.2 in f30.  Does anybody have a better idea?
Comment 68 Pablo Estigarribia 2019-07-20 14:45:13 UTC 
This works! 
https://copr.fedorainfracloud.org/coprs/kdudka/curl-next/

I have been able to open gnome-software and update apps from there. (updated curl using dnf update as gnome-software was just crashing with segfault)

If you happen to find a 25-hour day sometime soon, you could try bisecting it. Otherwise, if you think curl has a history of being safe and reliable to update, a rebase sounds pretty reasonable.

Perfect.  Thank you for testing it!

> If you happen to find a 25-hour day sometime soon, you could try bisecting it.

There are 573 commits between 7.64.0 and 7.65.2, so one can bisect it in 10 steps.  The actual problem is that nobody has provided a reliable reproducer.

> Otherwise, if you think curl has a history of being safe and reliable to update,

Not really.  It sometimes happens that a core functionality gets broken even in a point release.  For example, the 7.65.2 upstream release, which is known to fix this bug, is now already obsoleted by 7.65.3, because the progress meter was "unimplemented" by mistake in 7.65.2 ;-)

> a rebase sounds pretty reasonable.

Yes, in this case, we will most likely have to rebase.  I am not going to learn how to use gnome/flatpak/whatever to be able to bisect this bug...
