嘿各位，我最近碰到个大麻烦，想请大家支支招！我用Ubuntu 22.04已经三个月了，最近大部分Snap应用都打不开——Firefox、VS Code、软件中心这些常用的都没反应，只有Chrome这类非Snap的软件能正常运行，我的工作全靠这台笔记本，急死我了😭

具体问题细节 #

当我尝试打开Firefox时，图形界面完全没动静，于是我用终端启动它，得到了这个错误：

cannot perform operation: mount --rbind /dev/tmp/snap.rootfs_wq9l51//dev: No such file or directory

我试着运行sudo snap refresh，结果只有一个应用更新了，输出是：

notion-snap-reborn 1.0.28 from Maxime (sunshio) refreshed

为了排查问题，我运行了snap list --all，输出里能看到很多核心Snap包和应用都标记为broken或disabled，具体如下：

我已经试过的操作 #

• 运行sudo snap refresh，但只有notion-snap-reborn完成了更新，其他应用的问题依旧存在
• 尝试从终端启动Firefox，得到了上述挂载错误

有没有朋友遇到过类似的情况？或者有什么修复Snap核心组件、解决挂载问题的办法？麻烦大家给点建议，谢谢啦！
