OS/Web Information

• Web Browser:
• Local OS:
• Remote OS: Ubuntu
• Remote Architecture: x86_64
• code-server --version: 4.107.1 8c077bf with Code 1.107.1

Steps to Reproduce

Using the cli (example with ruff extension)

code-server --install-extension charliermarsh.ruff

Expected

I expect the latest version to be installed eg 2026.34.0. However an older one is installed : 2022.0.17

Actual

The newest version is installed only if I specify it.

code-server --install-extension charliermarsh.ruff@2026.34.0 --verbose

I observe the same behavior for other extensions like continue.continue or hediet.vscode-drawio.
