/dev/sda2 是我的根分区。我使用的是 SSD，它没有磨损。在 pop os 或 archlinux 中，dev-sda2.device 不会花费超过一秒钟的时间。

这是我的 fstab 文件：
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/sda2 during installation

# /boot/efi was on /dev/sda1 during installation

（顺便说一下，多媒体是我的硬盘的名称 - /dev/sdb）
如何解决这个问题？
答案1
删除 snapd
sudo apt remove snapd
修复。
注意：这将从 Ubuntu 中删除 snap
