• Kubewarden policy servers are crashing with the error:

"Cannot fetch Rekor keys from TUF repository TufMetadataError("Did not find exactly 1 active Rekor key")".

• The issue occurs after a certain period without any known updates to Kubewarden.

• This is a known bug, as mentioned in the Kubewarden policy server issue #1300.
  这是一个已知的 bug，正如 Kubewarden 策略服务器问题 #1300 中提到的。
• A fix has been implemented in policy server version 1.29.1+ to handle Sigstore init failures gracefully.
  在策略服务器版本 1.29.1+ 中已实现修复，以优雅地处理 Sigstore 初始化失败。
• With the fix in place, the policy server will no longer panic when something is wrong with Sigstore's TUF repository; it will simply inform the user that verification capabilities are not going to work at their full potential.
  修复完成后，策略服务器在 Sigstore 的 TUF 仓库出现问题时不会再慌乱;它只是会通知用户验证功能无法发挥全部作用。
• Refer to the release notes for more details.

• The crash happens because the policy server fails to fetch Rekor keys from the Sigstore TUF repository.

• In the affected Kubewarden version, these failures are not handled properly, resulting in the policy server crashing continuously.
