Short description of changes

Update the Coding Style Check yaml to specify ubuntu-24.04 as the runner, and to use apt-get to fetch shfmt instead of using snap to fetch it.

CHANGELOG: SKIP

Context: Fixes an issue?

Since sometime on 11 November, two things have happened that have caused Coding Style Checks to fail:

• The runner ubuntu-latest has moved from Ubuntu 24.04 to Ubuntu 26. This has caused the Python coding style check to fail consistently, which needs investigation.
• The Shell coding style check is failing because the Ubuntu snap store is currently unavailable online, and the Shell check uses snap to fetch shfmt. It is actually available from apt-get too, so there is no need to use snap.

Once the Python errors have been understood and fixed, we can revert to ubuntu-latest.

Walkthrough

The coding-style workflow now runs its C-like, Bash, and Python style jobs on Ubuntu 24.04. The Bash job installs shfmt with apt-get; its ShellCheck and formatting checks remain unchanged.

Full details: Title check

Explanation

The title names the main change: the Coding Style Check workflow is fixed so its CI jobs pass again. The diff pins the runner to ubuntu-24.04 and switches shfmt installation from Snap to apt-get, both of which address the failures. The title does not name the specific mechanisms, but it is accurate and specific enough for a reviewer scanning history.

Full details: Description check

Explanation

The description follows the repository template's main sections: short description, CHANGELOG, context, documentation need, status, and missing items. It states the change clearly: pin the Coding Style Check runner to ubuntu-24.04 and install shfmt with apt-get instead of snap. It gives the reasons: ubuntu-latest moved to Ubuntu 26, which breaks the Python check, and the Snap Store was unavailable, which breaks the Shell check. It also says the Python issue needs investigation before reverting to ubuntu-latest. The CHANGELOG entry is SKIP, the documentation answer is No, and the status is marked as tested. The template's optional AUTOBUILD line is not needed for this CI-only change. The description is complete enough for review.

Refresh the package index before installing shfmt.

If the runner image has a stale package index, apt-get install can fail before the shell style check runs. Run sudo apt-get update first, as GitHub recommends for hosted runners. (docs.github.com)

I see this PR didn't invoke the Coding Style Check, probably because there were no changed files of the types to check. I manually ran the action on my source branch here: https://github.com/softins/jamulus/actions/runs/43247490682

Do you want to try the -arm runner as we're changing it?

If not, just merge it.

I think it would be worthwhile to evaluate arm runners for compatibility and performance as a separate exercise. For now, I just wanted to get the CI working again.
