删除（清除）包apt-xapian-index会带来什么样的伤害？

我知道在清除apt-xapian-index之后你无法在Synaptic中使用快速filter，但有更严重的事情吗？

我知道有一些性能问题，当你拥有它时：

• https://bugs.launchpad.net/apt/+bug/363695
• https://bugs.launchpad.net/ubuntu/+source/apt-xapian-index/+bug/655831

Answer 1

没有什么严重的。 您可能会丢失某些function（请参阅下面的说明），但如果您不需要它，则可以删除该程序包（请注意不要卸载任何其他程序包）。 如果您后来发现这是一个错误，您可以再次安装它。

Description: maintenance and search tools for a Xapian index of Debian packages This package provides update-apt-xapian-index, a tool to maintan a Xapian index of Debian package information in /var/lib/apt-xapian-index, and axi-search, a command line search tool that uses the index. . axi-cache allows to search packages very quickly, and it also interfaces with the shell command line completion in a smart way, providing context-sensitive keyword and tag suggestions even before the search command is actually run. . update-apt-xapian-index allows plugins to be installed in /usr/share/apt-xapian-index to index all sorts of extra information, such as Debtags tags, popcon information, package ratings and anything else that would fit. . The index generated by update-apt-xapian-index is self-documenting, as it contains an autogenerated README file with information on the index layout and all the data that can be found in it. 

Answer 2

我删除了它，因为在一台八岁的电脑上，它有时会导致很好的挂断。 没有注意到任何不良影响。

Answer 3

这是一个已知的错误，但似乎没有问题出现删除它：

Answer 4
