重启我的 Ubuntu (22.04) 机器（进行了一些更新后）后，我无法打开 Firefox、Slack……以及我通过 snap 安装的大多数应用程序。经过 2 小时的调试，我选择了极端的解决方案，删除 snap 和 snapd，然后从头开始重新安装它们：
sudo apt autoremove --purge snapd && sudo apt autoremove --purge snap
然后：
sudo apt install snapd。
然后我安装了 snap-store：
snap install snap-store
当我在命令行中输入时snap store，出现错误：
error: cannot communicate with server: Post "http://localhost/v2/snapctl": dial unix /run/snapd-snap.socket: socket: permission denied
ERROR: not connected to the gnome-42-2204 content interface.
然后我尝试sudo systemctl restart snapd.service并验证 snapd 是否处于活动状态：
systemctl status snapd.service
输出：

我也遇到了 Chromium 的 snap-store 错误。我认为网络连接存在一些问题，但我真的不知道该怎么解决。任何见解都非常感谢。
