The problem is probably that and old version 2022.0.17 is installed.

If I uninstall, I see

When I click install, close the extension tab and reload it, I see

[MarcSkovMadsen]

If I run

$ code-server --install-extension charliermarsh.ruff@2026.34.0
Installing extensions on mnr-jupyterhub.de-prod.dk...
Updating the extension 'charliermarsh.ruff' to the version 2026.34.0
Installing extension 'charliermarsh.ruff' v2026.34.0...
Extension 'charliermarsh.ruff' v2026.34.0 was successfully installed.

Reload the window
Reopen the ruff extension tab

Run "Ruff: Restart Server"

Then it seems to work

[MichaReiser]

We've seen this behavior before, where VS Code falls back to an older extension when it can't find a more recent one compatible with your platform. But your Linux target is very generic, and we're definitely publishing releases for it (in fact, we publish artifacts for all supported targets except web)

I also found coder/code-server#7631

[ZaberKo]

Meet the same problem on Antigravity & Ubuntu24.04-WSL. When I install the latest ruff extension, it fallbacks to 2022.0.17

@ZaberKo

I ran into the same issue.
The workaround that fixed it for me was:

1. Right-click the extension
2. Select "Install Specific Version..."
3. Choose the latest version from the list
