我通过软件中心安装了一个 snap 应用程序 (Bookworm)。安装过程似乎很顺利，但当我尝试通过 GUI 启动它时什么也没发生。以下是我使用终端时发生的情况：
calixte@Ceres:~$ bookworm
[INFO 12:04:45.135623] Application.vala:154: Bookworm version: (null)
[INFO 12:04:45.135687] Application.vala:156: Kernel version: 4.15.0-21-generic
[WARNING 12:04:45.135986] [Gtk] Locale not supported by C library. Using the fallback 'C' locale.
Failed to register: GDBus.Error:org.freedesktop.DBus.Error.AccessDenied: Connection ":1.165" is not allowed to own the service "com.github.babluboy.bookworm" due to AppArmor policy
我该怎么做才能修复该错误并使应用程序运行？或者，我可以更改一般的 AppArmor 策略吗？
