vmware：Cannot open the disk 'XXX' or one of the snapshot disks it depends on. reason: failed to lock the file.

今天打开vmware的Ubuntu虚拟机，发现出现Cannot open the disk 'XXX' or one of the snapshot disks it depends on. reason: failed to lock the file警告，上网查了一下，发现原来是上次异常关机，原本文件夹里出现了.lck后缀的文件，将其所在的文件夹删除，就可以解决了。

 If this happens as the result of a crash, rather than intentionally as a “boot-clean” restart, and you’re trying to recover, then a less-destructive thing to try first would be to delete any .LCK folders within the main VM folder. If this works, you should get your system back in an up-to-date state.
