此问题出现在 Ubuntu 22.04 的启动过程中。尽管系统运行正常，没有任何明显的性能缺陷，但我一直遇到一系列与挂载单元故障相关的错误消息。系统检查报告以下内容：

这些消息表明在启动期间无法打开各种快照的 blockdev，随后无法安装其各自的单元。
虽然这些错误似乎不会影响操作系统的功能，但我担心可能存在一些可能不会立即显现的潜在问题。此外，我有兴趣了解这些错误的原因以及如何解决它们以实现更清洁的启动过程。
以下是我已经尝试过的故障排除步骤：
使用 fsck 检查文件系统是否有错误。确保所有 snap 包都更新到最新版本。尝试手动重新安装上述单元，但没有成功。如果您能对以下问题提供任何见解，我将不胜感激：
在启动过程中，这些错误消息的潜在原因是什么？有没有办法修复这些安装单元故障而不影响当前系统稳定性？这些错误是否表明即将发生需要采取先发制人行动的系统问题？任何建议或诊断建议都将不胜感激！
PS 这是我在 snap list --all 之后得到的结果：
snap list --all
