Apparmor 在 ubuntu 17.10 中初始化失败

安装 ubuntu 17.10 后，我在启动时开始收到此错误。以下是

答案1

我在我的三个 Ubuntu 17.10 系统上都遇到了完全相同的错误。似乎发生的是，apparmor 启动脚本返回错误，因为来自两个包“webbrowser-app”和“mediascanner2.0”的策略文件中存在错误。这两个包中的策略文件试图包含不存在目录中的文件。这是这两个包打包时出现的错误。从“sudo aa-status”的输出可以看出，该错误仅影响这两个包提供的策略。

解决方法是安装提供缺失目录的软件包“apparmor-easyprof-ubuntu”。安装此软件包后，我的系统上的错误消失了。

sudo apt install apparmor-easyprof # Ubuntu >= 18.04)

或者：

sudo apt install apparmor-easyprof-ubuntu # Ubuntu < 18.04

参考： https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/1554803

答案2

重新安装mediascanner2.0和删除webbrowser-app对我有用。

 sudo apt install --reinstall mediascanner2.0
 sudo apt purge webbrowser-app
 sudo apt autoremove --purge

答案3

我遇到了这个问题，并找到了以下解决方案：

apt install -y apparmor-easyprof-ubuntu
