The script fetches the Omakub installer with curl -fsSL and pipes it to bash.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟡 Moderate · up to 93d7c

This adds an Ubuntu setup action that executes mutable internet-delivered code and can report success after a failed download. Users could run changed remote commands or receive a false-success setup, so merge should wait for download verification and failure propagation, or explicit owner acceptance of these risks.

Use the POSIX wrapper shell.

This wrapper uses no Bash-specific syntax. Change the shebang to #!/bin/sh -e. Keep the explicit bash invocation for the downloaded installer only if that installer requires Bash.

As per coding guidelines, core/tabs/**/*.sh should prefer POSIX shell using #!/bin/sh -e and use Bash only when Bash-specific features are required.

- Line 3: Update the Omakub installation command to download the installer into
a temporary file, verify that the download succeeds, and only then invoke Bash
with the downloaded file; ensure curl failures are propagated as setup failures
instead of allowing Bash to succeed on empty input.
- Line 3: Replace the direct curl-to-bash pipeline in the Ubuntu setup script
with a pinned, trusted release download and verification step before execution;
enforce HTTPS-only redirects with curl’s proto-redir restriction or avoid
following redirects, and execute the downloaded artifact only after its checksum
or signature validates.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Propagate download failures to the setup result.

The pipeline reports the status of the final bash process, not curl. If curl is unavailable or fails before producing input, Bash can exit successfully on EOF. The setup can then report success without installing Omakub. Download to a temporary file, check the download status, and invoke Bash only after the check succeeds.
