升级到 20.04 后 NFS 无法启动

刚刚将我的媒体服务器从 18.04（Lubuntu）升级到 20.04。从那时起，NFS 共享就不可用了。我找不到任何关于如何处理以下问题的有用且最新的信息。看来 auth-rpcgss-module 和 rpc-svcgssv 服务没有运行；nfs-config 不再处于活动状态，但似乎已完成其任务并退出。在 list-dependencies 命令的输出中，这三个旁边有白点；其他的是绿色的。

显然这是某种安全问题。文件 /etc/krb5.keytab 不存在。某些 Kerberos 配置中是否有我需要更改的参数？

提前致谢！

已解决。重新安装了所有 nfs 包、rpcbind 等，重新启动后，NFS 共享现在可用。
