系统日志充满了这个错误消息，不和谐？

我注意到，如果我打开 Discord 应用程序，我的 /var/log/syslog 文件每秒都会不断被这些错误填满。这种情况会一直持续到我退出 Discord。然后停止。从这些消息中我所能理解的是，它们与 Discord 应用程序有关。

注意最后一行，我退出 discord 后，它不再推送错误。那么，你知道这是什么以及如何解决吗？

谢谢。

答案1

我在 18.04 中从 discord 收到的系统日志错误消息略有不同，但我怀疑原因可能是相同的。：

apparmor="DENIED" operation="open" profile="snap.discord.discord" name="/proc/2613/cmdline" pid=4255 comm="Discord" requested_mask="r" denied_mask="r" fsuid=1000 ouid=

我的错误似乎是由 discord 尝试检测我当前正在玩的游戏，以便它可以自动更新我的 discord 状态消息而导致的。您可以通过以下方式关闭此功能：

  1. 打开 Discord
  2. 点击用户设置在我的版本中，这是 discord 屏幕左下角的一个齿轮，上面有我的个人资料图片。

Discord 用户设置

  1. 点击游戏活动在下面应用程序设置在左侧。
  2. 关将当前正在运行的游戏显示为状态消息 在此处输入图片描述

如果关闭将当前正在运行的游戏显示为状态消息不起作用。那么你有三个选择：

  1. 给予 discord 所寻求的许可并承担隐私/安全风险：
    • 打开终端
    • 类型snap connect discord:system-observe
    • 更多信息，请参阅snapcraft-discord
  2. 修改 discord AppArmor 配置文件以抑制错误消息并承担兼容性/功能风险：
    • 打开终端
    • gedit admin:///var/lib/snapd/apparmor/profiles/snap.discord.discord
    • 通过在文件底部的}
      • deny /proc/@{pid}/cmdline r,
      • deny ptrace (read),
    • 保存并关闭 gedit
    • 通过输入以下命令加载新的 AppArmor 配置文件sudo apparmor_parser -r /var/lib/snapd/apparmor/profiles/snap.discord.discord
    • 信用 xNinjaKittyx
  3. 安装 discord 的 apt 版本
