KeepassXC 和 Chromium-browser 等多个应用程序在启动时崩溃。在我看来，Snap 中似乎存在错误。我在使用 Firefox 时也遇到了同样的问题，我将其从 Snap 控制中取出并用 deb 包替换后，问题就解决了。
KeepassXC 崩溃的原因：

这些信息可能很有用。我在使用 snap 时遇到了同样的问题：“无法根据更改挂载点更改挂载命名空间...权限被拒绝”
我找到了问题。这很奇怪。它与 AppArmor 相关联，后者负责保护 snap。在 Linux 中的 Home 目录中，我用指向另一个驱动器的同名符号链接替换了默认文件夹（图像、音乐、视频等）。看起来这导致了 AppArmor 的安全问题。我删除了符号链接并放回了文件夹，重新启动后 snap 现已启动。您可以将该解决方案应用于其他 snap。
