答案1
您可以关闭全部Snap 沙盒拒绝所有应用通过运行以下命令：
echo -n quiet_denied > /sys/module/apparmor/parameters/audit
这将抑制拒绝警告，直到下次启动。
如果您想使其永久生效，则必须使用 grub 指定内核参数。警告：这是一个高级更改，如果您不知道自己在做什么并将其搞乱，这可能会破坏您的系统！
在文件中，在 后面/etc/default/grub添加，如下所示：apparmor.audit=quiet_deniedGRUB_CMDLINE_LINUX_DEFAULT
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor.audit=quiet_denied"
然后运行
sudo update-grub
然后重新启动。
