[BUG] Snap crashes upon launch

[eeickmeyer]

All attempts to open QOwnNotes 23.10 snap fail to open. I suspect the snap is missing some runtime dependencies, possibly including kde-config-gtk-style which provides libcolorreload-gtk-module.so.

Expected behaviour

qownnotes launches normally.

Actual behaviour

qownnotes crashes upon launch.

Steps to reproduce

Install qownnotes snap:

• sudo snap install qownnotes

Launch qoownnotes:

• qownnotes

Terminal output:

Gtk-Message: 19:02:12.235: Failed to load module "colorreload-gtk-module"
Fontconfig warning: FcPattern object weight does not accept value [0 205)
Segmentation fault (core dumped)

Strange, I just tried installing it on a fresh Ubuntu instance, and it installed and ran as it should.

[dmatta22201]

I was having the same issue with the snap on a fresh minimal install of Ubuntu 23.10. To fix, I uninstalled the snap and installed using apt from the ppa, along with libcanberra-gtk-module. Works now.

[pbek]

I wonder why I wasn't able to reproduce this on Ubuntu 23.10... 🤔

Here's the log I get when starting 23.11.1. Definitly having the same issue as @dmatta22201 was. Gonna use their solution for now.

@YamiYukiSenpai, what Linux distribution did you use?

[pbek]

I still can't reproduce this on Ubuntu 23.10.

[eeickmeyer]

I still can't reproduce this on Ubuntu 23.10.

I'd say your testing might be flawed then if you're only using Ubuntu 23.10 as, with snaps, you should be able to use them in any Linux distribution (snaps aren't an Ubuntu-only thing, contrary to popular FUD/belief). Furthermore, per your screenshot, your Ubuntu 23.10 is out-of-date as it still shows "Development Branch" when Ubuntu 23.10 has been released for more than a month now and the release descriptor has been updated to no longer show "Development Branch".

My attempts to run have been mostly with Edubuntu 23.10 and Ubuntu Studio 23.10 (both of which are actually Ubuntu 23.10, but that shouldn't matter because a snap is a snap).

Additionally, did you install the snap locally (or using --devmode --dangerous)? If so, it might be using system libraries (in an unconfined state) and therefore not simulating how the snap would actually behave in the real world ("strict" confinement).

[pbek]

Since I only got one report which distribution was used (https://github.com/pbek/QOwnNotes/issues/2876#issuecomment-1776031182) I went with that and like you said, the snaps should run everywhere. The snap build process didn't change for quite a while, but it seems Ubuntu did.

Any help is much appreciated. And PRs for changes in https://github.com/pbek/QOwnNotes/blob/main/build-systems/snap/snapcraft/snapcraft.yaml and https://github.com/pbek/QOwnNotes/blob/main/snap/snapcraft.yaml are welcome.

And no, I just did the usual snap install qownnotes.

[tom-braun]

Same here. Kubuntu 23.10. Installed from snap. Fails to launch (Segementation Fault)

just guessing: @pbek, from you screenshot it seems you are running gnome? Could it be this is only effecting kde users? Are the failing-to-load gtk-modules a hint here?

[pbek]

Yes, for the test I used a fresh Ubuntu mainline install, because everyone was talking about Ubuntu (which is using Gnome by default). I used the Snap on KDE Neon (based on Ubuntu 22.04) for a long time and never had any issues, I wonder what Canonical (?) changed in 23.10 to even break a snap...

[pbek]

Kubuntu 23.10, LGTM

[github-actions[bot]]

This issue is stale because it has been open for 30 days with no activity.

[eeickmeyer]

Still same issue, Ubuntu Studio 23.10 (same DE as Kubuntu 23.10):

Gtk-Message: 13:09:11.166: Failed to load module "xapp-gtk3-module"
Gtk-Message: 13:09:11.278: Failed to load module "colorreload-gtk-module"

Segmentation fault (core dumped)

The segfault is the issue, but I have no way to know what the issue is that is causing the segfault. Per your screenshot, I note that you're still building the snap using core18? I must advise that core18 is no longer supported, you might need to update to core20 or core22.

[pbek]

Core18 was the highest version that snapcraft supported for a long time, I need to test of newer versions already work.

[eeickmeyer]

They should. I have a snap in which I had to manually patch electron to get up to core22. core18 went EOL in April. Each core version is only supported for 5 years, and core18 was released in 2018, core20 in 2020, and so on.

[pbek]

Meh, after fixing error after error with core22 I found out that there is no qmake plugin in core22 anymore 🙄

[pbek]

And with core20... error after error... And I can't even find an example on how you are supposed to build a Qt app with qmake on core20+. All I can find are using core18 or below...

[YamiYukiSenpai]

The KDE KF5 snaps?

[pbek]

Aren't those cmake?

[pbek]

After "only" a few days of work, I was able to get core20 working. 😅 It's in the edge channel, can you all please try to test it with snap install qownnotes --edge. I tested it on a fresh Ubuntu 23.10 installation, and it worked for me.

[eeickmeyer]

So, good news and bad news. Good news is it launches. Bad news is in the setup dialog, when I go to choose the folder for storing the notes, it crashes with:

(QOwnNotes:28018): GLib-GIO-ERROR **: 12:25:42.583: Settings schema 'org.gtk.Settings.FileChooser' does not contain a key named 'show-type-column'
/snap/qownnotes/11072/wrapper.sh: line 3: 28018 Trace/breakpoint trap   (core dumped) desktop-launch $SNAP/usr/bin/QOwnNotes -style=Breeze --snap

[pbek]

Wow, I saw a lot of messages on the internet on org.gtk.Settings.FileChooser crashing... 😬 Snaps are really a pita. 😬

[pbek]

I have no idea yet how to fix that core20 / Gnome / GTK / snap bug... The only working comment I found was Removing snap and installing from apt fixed the issue for me. 😆

[eeickmeyer]

🤣 🤣

I have a few snaps under my belt and might be able to play around with it too. I'd recommend trying for core22 since core20 only kicks the can down the road by two years and you'll revisit a similar problem. core22 would give it four.

And why GTK is even a factor here... 🤷

[pbek]

Core22 has no qmake plugin.

[eeickmeyer]

Core22 has no qmake plugin.

Perhaps, but you got it to build here: https://launchpad.net/~pbek/+archive/ubuntu/qownnotes?field.series_filter=jammy

There's zero difference between core22 and jammy since they're one in the same (Ubuntu 22.04). The difference is instead of qmake being a plugin, it becomes a build dependency.

[pbek]

That's the plan for the releases. But why do you mention that. Is there another difference between launchpad and https://snapcraft.io/qownnotes/builds that I forgot?

That's a good pointer. I'll do more GitHub code searches... 😁

[pbek]

I finally managed to get a snap with core22 working 😅 It was so much work! And... It still crashes when accessing the Gnome file dialog! 🤣

[eeickmeyer]

Try adding gnome-42-2204 as a plugin and see what happens.

[pbek]

I'm not sure if I want to pull the whole gnome snap inside QOwnNotes. 😬 Seems like others have the same issues with snaps: https://forum.snapcraft.io/t/app-crashed-when-openning-the-file-browser/31626

[eeickmeyer]

To be clear, it's not the entire GNOME desktop environment (not even shell or mutter), just a few core components. Most Electron apps use this anyway; it's just a few megabytes.

[pbek]

I'll try with libglib2.0-0 first... Why did Snaps get such a PITA 😬 ? I was such a Snap fan.

Most Electron apps use this anyway

QOwnNotes is a Qt app, not an Electron app nor a GTK app. 😁

[pbek]

Meh, error 500 when I open https://snapcraft.io/qownnotes/builds. 🙈

I'm well aware of this, but one trend I've had with Canonical lately (and I, as the lead for Ubuntu Studio have been having to fight them on) is that they've become very GNOME-centric and haven't thought about non-GTK possibilities. One lead engineer in particular had his mind blown when I told him that Qt themes and color schemes were completely detached from one another in KDE Plasma and that said color schemes could override the GTK color schemes; he couldn't fathom the concept.

So, yes, there are problems in the dependency chain, and unfortunately, there are only two of us (that are completely volunteer) trying to get this sorted.

[eeickmeyer]

Meh, error 500 when I open https://snapcraft.io/qownnotes/builds. 🙈

Gotta love temporary outages. :confounded:

[pbek]

It's 100x easier to create packages for even NixOS. https://github.com/NixOS/nixpkgs/blob/nixos-unstable/pkgs/applications/office/qownnotes/default.nix

I was even able to create UI (!) end2end tests easily (which I wasn't able to do anywhere yet): https://github.com/NixOS/nixpkgs/blob/nixos-unstable/nixos/tests/qownnotes.nix

[eeickmeyer]

There's a way to automate the entire process using Launchpad, believe it or not. Just requires mirroring your github repo to Launchpad and then Launchpad can do not only the building, but then it can upload straight to snapcraft.io to whichever channel you want (such as the edge channel), if that makes it easier.

[pbek]

That's what I do for releases. Only that I use https://github.com/pbek/QOwnNotes/blob/main/build-systems/snap/snapcraft/snapcraft.yaml as template and push directly to Launchpad.

I use https://snapcraft.io/qownnotes/builds to build from the main branch to edge.

I also build a snap in GitHub directly and push it to the snap store. 🤣

[eeickmeyer]

What I'm talking about is something like this: https://code.launchpad.net/ubuntustudio-system-installer

Just does it all for you and when you want an actual release, just go snapcraft release qownnotes {buildNumber} stable and you're done.

[pbek]

I've automated and semi-automated most of the stuff, like with https://github.com/pbek/QOwnNotes/blob/3a4f7258cb5a31c887f682f82ae4bb5803d41f8e/build-systems/snap/build-for-launchpad-snap.sh (which is called in a big tmux session inside a docker container) 😆 I think I could never decide what tool to settle on. https://snapcraft.io/ didn't exist back when I started, but I also tried to use it then in https://snapcraft.io/qownnotes/builds.

[pbek]

libglib2.0-0 brought success! Can you please try qownnotes from the edge channel again?

[eeickmeyer]

SUCCESS! IT WORKS!!!!

[pbek]

Finally!

[pbek]

Let's hope I added everything to my Launchpad snapcraft.yaml 😁

[pbek]

24.1.2

• the Snap version of QOwnNotes was (in a Herculean effort) migrated from Core18 to Core22 to cause less problems on Ubuntu 23.10 systems (for #2876)

[pbek]

There now is a new release, could you please test it and report if it works for you?

[pbek]

Keeping my fingers crossed for https://launchpad.net/~pbek/+snap/qownnotes/+build/2349541 to run through 🤞🏻

The GitHub build snap for amd64 works for me!

[eeickmeyer]

It's looking good! Just ran from the stable channel and all is good! I'll watch the launchpad build along with you. :)

[eeickmeyer]

Oops! Looks like that build failed, but looks like a simple fix.

[pbek]

It's looking good! Just ran from the stable channel and all is good!

Great, thank you for testing!

I'll watch the launchpad build along with you.

I forgot to comment out one line, we'll try with the next release... Those are the arm builds anyway. Out of the 3791 weekly active devices, only like 37 are on arm64. 😁
