Examples are NOT Working in Ubuntu

FYI

### 1
```bash
Task dev deno run -A --unstable --node-modules-dir npm:vite
failed to load config from /home/juan/dev/denoland-examples/with-react/vite.config.mjs
error when starting dev server:
TypeError: Invalid package specifier 'npm:react-dom/client@^18.2'. Did you mean to write 'npm:react-dom@^18.2/client'?
```
Easily soved by changing npm:react-dom/client@^18.2' to 'npm:react-dom@^18.2/client

### 2

But this one in unsolvable in ubuntu (but it works in w11)
```bash
Task dev deno run -A --unstable --node-modules-dir npm:vite
error when starting dev server:
Error: getaddrinfo ENOTFOUND localhost
