我在用Ubuntu 22.10在我的戴尔笔记本电脑 [英特尔 i3，amd64]。起初这个操作系统运行良好，但现在启动时间太长。当我sudo dmesg在终端中运行时，它显示以下输出：

这表明长时间运行的进程snap-store需要花费太多时间来执行. 似乎有任何与 snap-store 的政策相冲突。
我该怎么做才能解决这个问题。如果有人知道，请帮忙。

答案1
使用gparted，我发现根分区有两个挂载点，如下所示：
Mounted on /, /var/snap/firefox/common/host-hunspell
问题发生在snap 商店，所以为了给它一个小的解决方案，我只是删除了snap 商店从计算机中也删除了火狐（因为火狐安装于折断) 并从另一个平台安装了 Firefox。
然后重启。现在问题解决了。
