parsing current semver, skipping update check: %w

Error message

parsing current semver, skipping update check: %w

What it means

After parsing the latest remote version, getLatestAndCurrentVersion parses the running binary's own version (version.Get().Version) as semver. This error means the current binary's version string is not valid semver, so a safe update comparison is impossible. The 'skipping update check' wording signals the check is abandoned intentionally.

Solutions

1. Rebuild skaffold with proper ldflags, e.g. -X github.com/GoogleContainerTools/skaffold/pkg/skaffold/version.version=vX.Y.Z.
2. Install an official release instead of a source build (gcloud components or GitHub release binary).
3. If you build from source routinely, set the version variable in your build script to 'git describe --tags' output.
4. Treat it as non-fatal: the message already says the update check is skipped; only address if you rely on auto-update.

Example fix

// before
go build -o skaffold ./cmd/skaffold
// after
go build -ldflags "-X github.com/GoogleContainerTools/skaffold/pkg/skaffold/version.version=$(git describe --tags --always | sed 's/^v//')" -o skaffold ./cmd/skaffold

if !semver.IsValid(strings.TrimPrefix(version.Get().Version, "v")) {
    log.Debug("built from source without version ldflag; skipping update check")
    return none, none, nil
}

func hasValidBuildVersion(v string) bool { return semver.IsValid(strings.TrimPrefix(v, "v")) }

_, current, err := getLatestAndCurrentVersion(ctx)
if err != nil && strings.Contains(err.Error(), "parsing current semver") {
    // dev build; ignore
}

When it happens

Trigger: version.ParseVersion(version.Get().Version) errors — typically when skaffold was built from source without the version ldflag, yielding strings like 'v0.0.0-unknown', 'dev', or empty.

Common situations: Running a locally built skaffold (go install / git checkout) without ldflags injecting a semver; nightly/custom builds with non-semver version metadata; embedding skaffold as a library with a default version value.
