Summary

Both Linux builds in the failing run reached CMake without libnotify after the cached APT install failed. The fallback installed GTK and WebKitGTK, but left libnotify missing.

Type of change

• Bug fix (non-breaking change fixing an issue)

Affected modules / scope

• Other: Linux CI dependency setup in .github/actions/setup-dependencies/action.yml

This is based on core and can be reviewed separately from #444.

Changes introduced

• Replace the cached APT install and partial fallback with apt-get update followed by a direct install. Keep the full package list and normal APT recommendations, and stop the step if installation fails.
• Use libgdk-pixbuf-2.0-dev, which is available on both runner distributions. The old name is transitional on Ubuntu 24.04 and absent from Ubuntu 26.04.
• Check gtk+-3.0, webkit2gtk-4.1 and libnotify together before the native build, so GTK being present cannot hide a missing dependency.

Fixes #445.

Checklist

• Follows the existing YAML and shell conventions.
• Includes only changes relevant to this issue.
• Full hosted workflow and downstream managed tests pass (not rerun yet).

Additional context

I ran the action's exact Linux shell block in clean Ubuntu 26.04 x64 and Ubuntu 24.04 ARM64 containers, with ARM64 running under emulation. Both passed dependency installation, all three module checks and GUI smoke checks. Native Release builds with test exports also passed on both architectures, using CMake 4.4.0 and Node 24.22.2.

Actionlint 1.7.12, Bash syntax checks and failure-propagation checks passed as well. The latter confirmed that APT update/install errors and a missing required module stop the step.

These were local container checks. The full workflow still needs a run on GitHub's hosted runners.

Is there a particular reason why you choose to step away from the cached approach?
The reason why I originally cached them was due to longer config times without the caching

[JoarEliasson]

Fair point, and no good reason. The cached step was the part that failed, so I swapped it for a plain install without checking what that costs.

I looked at the logs again and I think the cache can stay. On x64 the action choked on libgdk-pixbuf2.0-dev, which no longer exists on Ubuntu 26.04. On ARM64 the package lists were stale, so the downloads 404'd. Renaming that package and running apt-get update before the cached step should cover both. I'd keep the check for all three libraries as a safety net, since the action reports success even when it installs nothing.

I'll rework the PR that way if that sounds OK to you.

I'll leave the nuget caching issue for another day, as it is a bit too difficult to setup in a project like this on a whim
