升级到Ubuntu 20.10后的绊线分割故障

Question

昨天升级到Ubuntu20.10之后，tripwire在其文件系统扫描和我运行tripwire --init时都一直在分段错误。

当我运行tripwire --init --verbose时，我得到以下信息

我已卸载和重新安装，但没有任何效果。

后续(添加于2020年10月28日)：我决定从源代码(可用的这里)构建和安装，并且安装和初始化都很好。

正如普雷斯顿中士常说的，“这个案子已经结案了。”

Answer 1

/usr/sbin中的文件或目录权限可能导致这种情况。我在20.04中也遇到了类似的问题，其中有一个400权限的文件导致了这种情况。我只是简单地添加了排除，它在更新我的twpol.cfg之后就能工作了。
