STM32CubeIDE For Visual Studio Code extension not installing correctly

I have spent about 1 day trying to get the latest pre-release version of the extension to install correctly. If only appears to be installing 2 of the bundled extensions, Memory Inspector and CMake Tools, out of the 15 extensions that are included in the bundle. No extension icon is appearing in the left panel and when I go to Settings/Extensions the extension is not listed.

I've read another thread of someone reporting the same problem, but I could not determine a concrete solution.

Is there a way to manually install this extension and the extensions in the bundle?

@infinitemac I have been able to reproduce; I see a lot of HTTP 404 error into the logs by getting most of our extensions, meaning "not found" from HTTP protocol while extensions are here and manual install is possible...

Since "extension pack" support from VSCode looks unstable for now there is no easy way to get the list.

You could eventually install the pack and check within local metadata in _userDir_/.vscode/extensions/stmicroelectronics.stm32-vscode-extension-3.6.3/package.json, but pasting here the list for you:

"extensionPack": [
	"STMicroelectronics.stm32cube-ide-core",
	"STMicroelectronics.stm32cube-ide-bundles-manager",
	"STMicroelectronics.stm32cube-ide-build-cmake",
	"STMicroelectronics.stm32cube-ide-build-analyzer",
	"STMicroelectronics.stm32cube-ide-project-manager",
	"STMicroelectronics.stm32cube-ide-debug-core",
	"STMicroelectronics.stm32cube-ide-debug-generic-gdbserver",
	"STMicroelectronics.stm32cube-ide-debug-stlink-gdbserver",
	"STMicroelectronics.stm32cube-ide-debug-jlink-gdbserver",
	"STMicroelectronics.stm32cube-ide-rtos",
	"STMicroelectronics.stm32cube-ide-registers",
	"STMicroelectronics.stm32cube-ide-clangd",
	"eclipse-cdt.memory-inspector",
	"eclipse-cdt.serial-monitor",
	"ms-vscode.cmake-tools"
]

For the rest we need some hint from the Marketplace owner.

UPDATE: the issue is under analysis and tracked by https://github.com/microsoft/vsmarketplace/issues/1454

Something weird looking at VSCode marketplace.

STM32CubeIDE for Visuql Studio Code pack is claiming x15 extensions but only x2 displayed (and installed you're right same on my side ... despite was ok 2 days ago and no update published according changelog since)

The very same applies to ARM Keil Studio pack which is claiming x4 extensions but only x2 displayed (couple of days ago I was getting the four ones ...)

Microsoft as usual suspect ???

Installing them all one by one is populating the pack display what kind of demo pack itself is ok ... first time ever facing this behavior kind.

How can I find the list of extensions in the bundle, so that I can install them manually?
