Root Cause

Helm client and Tiller/server versions are mismatched, or in Helm v3, the installed chart version is not compatible with the cluster's Helm SDK version due to API changes.

中文

Helm客户端和Tiller/服务器版本不匹配，或者在Helm v3中，安装的chart版本与集群的Helm SDK版本因API变更而不兼容。

Dead Ends

Common approaches that don't work:

  1. 65% fail

    --force only reapplies resources; does not fix version incompatibility; may cause resource conflicts.

  2. 80% fail

    Cluster downgrade is risky and may break other services; not practical for production.

  3. 50% fail

    Reinstall doesn't change the server version; the cluster's Helm SDK is embedded in the tiller or in-cluster agent.
