update-apt-xapian-index 上次运行是什么时候？

Question

我如何知道update-apt-xapian-index上次运行的时间？有什么办法可以知道吗？

Answer 1

您需要的命令是axi-cache info. 您可以查阅其手册页或内置帮助。

但主要问题是由于错误 1612948在 16.04 LTS、18.04 LTS 和更新版本上开箱即用。它返回错误消息而不是所需的输出：

$ axi-cache 
No module named 'ConfigParser': only help functions are implemented, for the sake of help2man

引用 Brian Murray对错误 1760608 的评论

布赖恩·默里 (brian-murray) 在 2018-04-06 上写道：#4

正确的解决方法是将axi-info中的import修改为“from ConfigParser”为“from configparser”。如果有人创建了 debdiff，我很乐意赞助它。

所以我们可以使用我对错误 1612948 的评论中的原始建议

sudo sed -i 's/from ConfigParser import RawConfigParser/from configparser import RawConfigParser/' /usr/bin/axi-cache

手动修补后，它将起作用（从 16.04 LTS 输出）：

$ axi-cache --help
Usage: axi-cache [options] command [args]

Query the Apt Xapian index.

Commands:
...
     axi-cache info      print information about the apt-xapian-index environment
...

所以我们需要 Ubuntu 开发人员的回复和/或行动来应用这些修复。
