could not determine latest version; check https://github.com

Error message

could not determine latest version; check https://github.com/multica-ai/multica/releases/latest

What it means

The update command is not running under Homebrew, so it needs the latest release tag from cli.FetchLatestRelease() to build the download URL — but that call failed earlier (a warning was printed: 'could not check latest version'), leaving `latest == nil`. Without a tag there is nothing to download, so the command aborts and points the user at the GitHub releases page.

Solutions

1. Check network/proxy access to https://api.github.com and https://github.com/multica-ai/multica/releases.
2. Retry once transient network conditions or rate limits clear (unauthenticated GitHub API is limited to 60 req/h).
3. If a GITHUB_TOKEN-style mechanism is supported by your setup, use it to raise the rate limit.
4. As a workaround, download the binary manually from the releases page the error links to.

curl -fsS --max-time 10 https://api.github.com/repos/multica-ai/multica/releases/latest >/dev/null \
  && echo 'github reachable' || echo 'github unreachable: update will fail'

for i in 1 2 3; do multica update && break; echo "attempt $i failed (likely network)"; sleep 30; done

When it happens

Trigger: Running `multica update` on a non-brew install while GitHub API/releases are unreachable (offline, proxy blocking api.github.com, rate limit) — the earlier FetchLatestRelease error is downgraded to a warning, then this guard fires at the download step.

Common situations: Corporate proxies or sandboxes that block api.github.com, GitHub API rate limiting from shared IPs, DNS failures, or air-gapped machines.
