最近，我安装的 Ubuntu 上的每一个 snap 包都停止工作了。
当我尝试在控制台中运行它们时，我会收到错误：
snap-confine has elevated permissions and is not confined but should be. Refusing to continue to avoid permission escalation attacks
我尝试重新安装 snapd、snap-confine 和 apparmor。还安装了 apparmor-easyprof 包。但这些都无法解决问题。
重新安装 snap 后，当我尝试安装新的 snap 时出现此错误：
error: cannot perform the following tasks:
- Setup snap "snapd" (11402) security profiles (cannot setup profiles for snap "snapd": cannot create host snap-confine apparmor configuration: cannot reload snap-confine apparmor profile: cannot load apparmor profiles: exit status 1
apparmor_parser output:
Found reference to variable multiarch, but is never declared)
当我尝试检查 apparmor 的状态时，aa-status唯一的输出是apparmor module is loaded.应该有更多的配置文件被加载并在状态中可见，据我所知。
的输出systemctl status apparmor为：
Loaded: loaded (/lib/systemd/system/apparmor.service; disabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Tue 2021-03-30 18:51:05 EDT; 34min ago
