Edit the file product.json in folder /usr/lib/code replacing this:

	"extensionsGallery": {
		"serviceUrl": "https://open-vsx.org/vscode/gallery",
		"itemUrl": "https://open-vsx.org/vscode/item"
	},

with this:

	"extensionsGallery": {
		"serviceUrl": "https://marketplace.visualstudio.com/_apis/public/gallery",
		"itemUrl": "https://marketplace.visualstudio.com/items"
	},

Tested and working well.
