我的机架中的规范实时补丁图标开始显示红色“！”符号，打开窗口时，我收到错误消息“规范实时补丁遇到内部错误。请参阅https://wiki.ubuntu.com/Kernel/Livepatch#CommonIssues了解更多信息。”。
我进行了一些挖掘，以下是运行以下命令后得到的日志：
journalctl-f-t 规范-livepatch

我曾尝试进入并删除 /var/snap/canonical-livepatch/common/locks 中提到的文件，但即使重新启动，仍然出现相同的错误。
我目前正在运行 Ubuntu 20.04 LTS。

删除livepatch_Ubuntu_5_4_0_39_43_generic_69_69.1重复后sudo canonical-livepatch refresh，它对我有用。
