Unable to run playground on Debian Linux by following docs

[visortelle]

I installed tiup by using docs on this page: https://docs.pingcap.com/tidb/stable/quick-start-with-tidb/

tiup playground command constantly failed with the following error:

Checking updates for component playground... Timedout (after 2s)
The component `playground` version  is not installed; downloading from repository.
Warn: invalid signature for file root.json: not enough signatures (2) for threshold 3 in root.json
Error: no trusted root in the local manifests

Running tiup update --all fixed the issue. It was simple to fix, but still took a few minutes, which isn't good for quick-start.
