⚠ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: pubspec.lock

Command failed: docker run --rm --name=renovate_a_sidecar --label=renovate_a_child --memory=3584m -v "/tmp/worker/8231dc/1351d0/repos/github/canonical/ubuntu-desktop-installer":"/tmp/worker/8231dc/1351d0/repos/github/canonical/ubuntu-desktop-installer" -v "/tmp/worker/8231dc/1351d0/cache":"/tmp/worker/8231dc/1351d0/cache" -e CONTAINERBASE_CACHE_DIR -w "/tmp/worker/8231dc/1351d0/repos/github/canonical/ubuntu-desktop-installer" ghcr.io/containerbase/sidecar:9.23.4 bash -l -c "install-tool dart 3.1.4 && dart pub upgrade flutter_lints"
Because ubuntu_desktop_installer_workspace requires the Flutter SDK, version solving failed.

Flutter users should run `flutter pub get` instead of `dart pub get`.
