我在 fedora 26 上运行 subsonic（一种媒体服务器 Web 服务）。我最近在升级到 F26 期间发生了电源故障。我不得不修复很多事情，包括 selinux 上下文、替换一些应用程序等……但能够恢复并完全运行，除了这个亚音速媒体服务器。

然后我成功地重新升级到 F26。

当我开始亚音速时，我在它的日志中得到以下错误，重要的部分是“org.apache.http.ssl.SSLInitializationException: TLS SSLContext not available”

我重新安装了应用程序并返回了一些修订版，没有运气。还重新安装了 openjdk、openssl 和其他一些软件包，但没有成功。

然后我检查了 cacerts 文件，但我无法使用 keytool 打开它：

keytool -list -keystore -v /etc/pki/java/cacerts

这给了我一个错误：“java.security.KeyStoreException: JKS not found”“

然后我重新安装了 ca 证书，认为它可能已损坏。没运气。

除了完全重新安装还有什么建议吗？我有我的数据备份，但宁愿先找出问题所在。

猜测功率损失比预期的更灾难性。我不得不重新安装 java-1.8.0-openjdk-headless 而不仅仅是 java-1.8.0-openjdk 来纠正这个问题。我不确定到底是什么损坏了。想知道我还有什么惊喜！
