如果我在 Ubuntu 上执行更新:
sudo apt-get update
我只进行某些文件中指定的更新。这个文件是什么?(抱歉,如果此主题已经重复)
也许我应该把我的问题表述得更清楚一些。我搜索一个文件,其中给出了我更新的所有路径

阅读 apt-get 手册页可以找到答案。
man apt-get
update
update is used to resynchronize the package index files from their
sources. The indexes of available packages are fetched from the
location(s) specified in /etc/apt/sources.list. For example, when
using a Debian archive, this command retrieves and scans the
Packages.gz files, so that information about new and updated
packages is available. An update should always be performed before
an upgrade or dist-upgrade. Please be aware that the overall
progress meter will be incorrect as the size of the package files
cannot be known in advance.
也就是说,从文件或目录apt-get update
中找到的所有存储库中获取包列表,并使用有关包及其依赖项的最新版本的信息更新本地数据库。/etc/apt/sources.list
/etc/apt/sources.list.d
