Snap crashes with Segmentation fault (core dumped)

[kspearrin]

• Version: ^20.15.1

• Target: --linux --x64

We have been publishing our snap in the past without issue. We recently updated to electron 2.0.2 and builder 20.15.1 and now we get the following crash when trying to run a built snap. This seems to happen on Ubuntu 16, 17, and 18.

$ snap run myapp
Gtk-Message: Failed to load module "canberra-gtk-module"
Gtk-Message: Failed to load module "canberra-gtk-module"

The Gtk errors are normal. A long pause of ~15 seconds happens. Then I see the app window appear for a split second and then.

Segmentation fault (core dumped)

This issue seems related, but was said to have been fixed.

Reference app: https://github.com/bitwarden/desktop

Building AppImage works and runs fine.

@kspearrin Have you managed to fix it? I'm experiencing the same issue.

[develar]

@DimitarNestorov Do you build on Linux?

[DimitarNestorov]

@develar No (I use the template, on macOS). But I will try that now

[develar]

Ok... Please set env _REMOTE_BUILD=true does it help? If not, please "Is option useTemplateApp (under snap) help you?" (only on Linux or macOS with Docker).

[develar]

If your app has native deps and no prebuild, you can build only on Linux.

[kspearrin]

@DimitarNestorov @develar Have not found a fix yet. We build on Ubuntu.

[DimitarNestorov]

Tried _REMOTE_BUILD=true, didn't work.
Tried "useTemplateApp": true on Ubuntu, didn't work.
Tried "useTemplateApp": false on Ubuntu, 2 hours later, didn't work.

[develar]

Do you have native deps?

[kspearrin]

Yes, see the repo mentioned in the original issue: https://github.com/bitwarden/desktop

[DimitarNestorov]

Do you have native deps?

No.

[DimitarNestorov]

I'm using the package @sentry/electron@0.5.4 for error tracking. Calling it's init method is the cause of this error on my app.

[develar]

@DimitarNestorov So, it is app specific issue?

[DimitarNestorov]

@develar Yes: getsentry/sentry-electron#98

[kspearrin]

@develar Any reason why this was closed? My original issue still remains. I am not using the referenced sentry-electron package.

[develar]

@kspearrin "reply needed" was added to get answer from you. And now you have answered :)

[DimitarNestorov]

I just tried building electron-quick-start with your snap configuration and it worked

You should check out your runtime code for something similar to my issue.

[develar]

@kspearrin please check your app works as unpacked / AppImage.

[kspearrin]

@develar Yes, it does. We are distributing it already as an AppImage under that version.

[develar]

@kspearrin have you tried useTemplateApp: false?

[kspearrin]

@develar Yes, it made no difference. See https://github.com/bitwarden/desktop/blob/master/package.json#L178

[kspearrin]

@develar Is there a way for me to get more feedback about what's crashing the app here other than just "Segmentation fault (core dumped)" . It doesn't seem to be very helpful.

[kspearrin]

@develar Updated to electron 2.0.5 and builder ^20.25.0 , but it made no difference. Same problem still. Can this be reopened please?

[kspearrin]

@develar I've spent today trying to debug this issue more.

I placed console.log message all throughout the app startup process and I can see that the main process executes without issue. The BrowserWindow is created, index.html loaded, and window.show() without any error.

Then Segmentation fault (core dumped) error happens when the window first appears and application crashes.

[DimitarNestorov]

Do you mind commenting the contents of the init method of src/main/powerMonitor.main.ts and test again?

[kspearrin]

@DimitarNestorov It works now after commenting out the references to power monitor, which has references to desktop-idle (a native module). Thanks for the tip.

@develar Any reason why desktop-idle won't work with snaps anymore? It used to. Do I need to add some stage package for it? Their docs say:

Linux Requirements
X server development package and pkg-config are required:
apt install libxss-dev pkg-config

I have these installed on the local dev machine that I am building from.

[DimitarNestorov]

No, that is not the issue.
This is the issue: electron/electron#13767

[kspearrin]

@DimitarNestorov Thanks. Fixed with bitwarden/desktop@fea8ab5 for now. Closing since this is an electron bug.
