fix(ci): install snapcraft via snap instead of apt-get

[Copilot]

snapcraft is no longer available as an apt package on ubuntu-latest runners, causing the "Tag release" workflow to fail with E: Unable to locate package snapcraft.

Change

• .github/workflows/release.yaml: Replace the broken apt-based install with the officially supported snap install:

- run: sudo apt-get -yq --no-install-suggests --no-install-recommends install snapcraft
+ run: sudo snap install snapcraft --classic

Original prompt

The "Tag release" workflow (.github/workflows/release.yaml) is failing at the "Install Snapcraft" step because snapcraft is no longer available as an apt package on the ubuntu-latest runner image.

Error from the job logs:

E: Unable to locate package snapcraft

Fix: On line 17 of .github/workflows/release.yaml, replace:

run: sudo apt-get -yq --no-install-suggests --no-install-recommends install snapcraft

with:

run: sudo snap install snapcraft --classic

Snapcraft is distributed as a snap package and should be installed via snap install rather than apt-get.

Failing Job Analysis

The job fails at the "Install Snapcraft" step because the snapcraft package is not available via apt-get on the ubuntu-latest runner image:

E: Unable to locate package snapcraft

Snapcraft is distributed as a snap, not as a deb package, so apt-get install snapcraft no longer works on newer Ubuntu runner images.

Solution

Replace the apt-get install step with a snap-based installation using the dedicated snapcore/action-build action, or simply install it via snap. Here's the minimal fix in .github/workflows/release.yaml:

     - name: Install Snapcraft
-      run: sudo apt-get -yq --no-install-suggests --no-install-recommends install snapcraft
+      run: sudo snap install snapcraft --classic

This installs Snapcraft via its officially supported distribution method (snap) and should resolve the failure.

User: Open a PR for this.

Assistant: I've kicked off the coding agent to create a PR that replaces sudo apt-get install snapcraft with sudo snap install snapcraft --classic in the release workflow. You'll be prompted to confirm once the PR is ready.
