GTK+ module libcanberra-gtk-module.so cannot be loaded

[Petros626]

Hello guys,

I'm using OpenCV in VSCode (Ubuntu Software installation) and everything worked fine, until I updated my libraries (sudo apt-get update/upgrade/full-upgrade) I guess. But now VSCode or rather OpenCV can't find the GTK library.

I've tested this succesfully:
GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-2.0 ./test --> works

But when I specify the version gtk-3.0:
GTK_PATH=/usr/lib/x86_64-linux-gnu/gtk-3.0 ./test --> fails

Normally the loaded version without using GTK_PATH is gtk-3.0 and then it shows me this error:

I verified that the in /usr/lib/x86_64-linux-gnu/gtk-3.0/modules is:

Would appreciate to solve this warning and to understand why the .so cannot be loaded.

Thanks in advance

UPDATE: the example code can be executed without warnings in the normal gnome terminal, but VSCode seems to habe problems to find the specific libraries, so it's definitely VSCode.

Any timeline for getting a fix for this issue and #179274 ?
Currently VSCode is unusable on fresh Linux Installs when trying to configure GitHub extensions as it fails to launch the system browser.

[Petros626]

Yeah this could be a solution, but in my case I reinstalled VSCode with the deb package and not with Ubuntu Software. Seems snap occurs the problem.

I will keep this issue open to address the problem with snap packages.

This bug has been fixed in the latest release of VS Code Insiders!

@Petros626, you can help us out by commenting /verified if things are now working as expected.

If things still don't seem right, please ensure you're on version a572746 of Insiders (today's or later - you can use Help: About in the command palette to check), and leave a comment letting us know what isn't working as expected.

Happy Coding!

This requires author verification.

@Petros626 can you help confirm if this issue is resolved in latest insiders of snap ?

snap install code-insiders --classic

Hey I'm not able to access the pc I've used for this work. How else could we verify it?

[deepak1556]

No worries, I have removed author verification. We might not be able to verify the OpenCV setup but following steps would work as well from #179274 (comment)

Steps for verification:

• Install VSCode Insiders snap package
• Install GIMP from ubuntu software store
• Open integrated terminal
• Launch gimp and confirm the errors reported in Undefined Symbol Error while trying to launch GUI Apps from a Snap Installed VSCode Built-in Terminal #179274 (comment) is not displayed in the terminal.

With the verification steps above, I get a single message Gtk-Message: <timestamp>: Failed to load module "canberra-gtk-module", but that's it.

Okay glad to hear that.

[AmeyaVS]

Is this integrated in stable release?

[rzhao271]

@AmeyaVS the change is in the latest Stable release. Let us know if you're still seeing the issue.

I am still observing this issue on my system here's the details from the VSCode versions:

Version: 1.80.0
Commit: 660393deaaa6d1996740ff4880f1bad43768c814

OS: Linux x64 6.3.11-200.fc38.x86_64 snap

I still need to unset the GTK_PATH environment variable to launch any GTK+ Application as captured here: #179274.

[deepak1556]

@AmeyaVS are you seeing the error with same steps from #179274 (comment) ? Can you share the output of the following steps,

1. Launch VSCode
2. Delete any terminal related settings to unset GTK_PATH
3. Open integrated terminal
4. Run printenv

@AmeyaVS are you seeing the error with same steps from #179274 (comment) ? Can you share the output of the following steps,

The failure still exists, also I am unable to configure GitHub Account credentials on my VSCode as Firefox fails to launch from VSCode due to the same reasons.

1. Launch VSCode

2. Delete any terminal related settings to unset `GTK_PATH`

I don't have it unset in any VSCode settings. This is a new installation.

3. Open integrated terminal

4. Run `printenv`

Here's the grepped GTK/VSCODE Environment variables captured on my system in the integrated terminal:

XDG_CONFIG_DIRS_VSCODE_SNAP_ORIG=
GDK_BACKEND_VSCODE_SNAP_ORIG=
GIO_MODULE_DIR_VSCODE_SNAP_ORIG=

GTK_IM_MODULE_FILE=/home/ameyavs/snap/code/common/.cache/immodules/immodules.cache
LOCPATH_VSCODE_SNAP_ORIG=

I don't have any of the GTK* Evironment Variables in my default system terminal.
It seems the issue is not resolved.

[AmeyaVS]

Is there a timeline for this issue to be fixed?

[AmeyaVS]

Any updates?

[deepak1556]

The terminal agents are inheriting the environment from the snap shell which gets adjusted with our custom GTK env variables, so this is no longer trivial to solve. It might take a while before I get to address this issue. I recommend using external terminal with snap or if you need integrated terminal then please switch to the debian package.

This affects all Linux ArduPilot users of MAVProxy in VSCode.

Manually calling unset GTK_PATH can fix it in each terminal session.

We use Linux for development because of the difficulty of using hardware debuggers in WSL.

[AmeyaVS]

I would like to add it seems now a new environment variable GIO_MODULE_DIR is causing other gtk based applications running from Snap installed VSCode Built-in Terminal is breaking them, and the symptoms are similar to issue #179274.

Is there any timeline for getting any fixes for the snap package?
