LivePatch错误失败“无法应用修补程序:锁文件已经存在”

Question

在我的货架上的典型活补丁图标开始显示一个红色"!“符号和打开窗口时，我得到错误消息“规范的Livepatch经历了一个内部错误。请参考https://wiki.ubuntu.com/Kernel/Livepatch#CommonIssues获得更多信息。”

我仔细研究了一下，下面是运行以下命令后获得的日志：

-f -t规范-livepatch

sudo规范-livepatch刷新

checking for patches
nothing to apply
kernel: 5.4.0-39.43-generic
patch state: ✗ the application caused a crash last time it was applied, check system logs with `journalctl -f -t canonical-livepatch`
patch version: 69.1

我尝试过进入和删除/var/snap/正则-livepatch/公用/锁中提到的文件，但是即使在重新启动时，仍然会出现相同的错误。

我目前正在运行Ubuntu20.04LTS。

删除livepatch_Ubuntu_5_4_0_39_43_generic_69_69.1重复sudo canonical-livepatch refresh之后，它对我起了作用。
