Aptitude 在哪里记录警告？

没有任何 - 默认情况下 aptitude 不会将错误或警告写入磁盘。所有的内容/var/log/aptitude都是安装。

如果您想要额外的日志记录，您需要说明aptitude这一点。

来自man aptitude：

   --log-file=<file>
       If <file> is a nonempty string, log messages will be written to it, except that if
       <file> is “-”, the messages will be written to standard output instead. If this option
       appears multiple times, the last occurrence is the one that will take effect.

       This does not affect the log of installations that aptitude has performed
       (/var/log/aptitude); the log messages written using this configuration include
       internal program events, errors, and debugging messages. See the command-line option
       --log-level to get more control over what gets logged.

       This corresponds to the configuration option Aptitude::Logging::File.

   --log-level=<level>, --log-level=<category>:<level>
       --log-level=<level> causes aptitude to only log messages whose level is <level> or
       higher. For instance, setting the log level to error will cause only messages at the
       log levels error and fatal to be displayed; all others will be hidden. Valid log
       levels (in descending order) are off, fatal, error, warn, info, debug, and trace. The
       default log level is warn.

       --log-level=<category>:<level> causes messages in <category> to only be logged if
       their level is <level> or higher.

       --log-level may appear multiple times on the command line; the most specific setting
       is the one that takes effect, so if you pass --log-level=aptitude.resolver:fatal and
       --log-level=aptitude.resolver.hints.match:trace, then messages in
       aptitude.resolver.hints.parse will only be printed if their level is fatal, but all
       messages in aptitude.resolver.hints.match will be printed. If you set the level of the
       same category two or more times, the last setting is the one that will take effect.

       This does not affect the log of installations that aptitude has performed
       (/var/log/aptitude); the log messages written using this configuration include
       internal program events, errors, and debugging messages. See the command-line option
       --log-file to change where log messages go.

       This corresponds to the configuration group Aptitude::Logging::Levels.

[编辑] 好吧……试图引导你去喝水并让你喝水花了太长时间：

/etc/apt/apt.conf.d/50aptitude只需创建包含以下内容的文件- 这也将使您不必使用命令行开关：

Aptitude::Logging::File "/var/log/aptitude.out";
Aptitude::Logging::Levels "*:info";

这对我有用：

每当我调用Aptitude时，我都会使用

aptitude --log-file=/tmp/AptitudeLog.log --log-level=info

然后，因为如果我需要任何关联的日志信息，我永远不会记得在哪里查找，所以我在/var/log和中留下了上述临时日志文件的链接/var/log/apt

问题结束！
