“apt-get update”给出了很多错误 – 这是一个问题吗？
我刚刚再次运行了sudo apt-get update ，我认为在输出中有很多行以Ign开头而不是Hit 。
我想知道它对Ask Ubuntu和超级用户的意义和研究，但他们有相互矛盾的答案。 在与@Seth讨论聊天和一些逻辑思维后，我得出结论：
-
Hit意味着“此包索引列表已下载并且是最新的” -
Ign表示“无法下载此索引列表，例如由于错误404（未找到）。但是，错误可以忽略，因为只缺少翻译，但程序包仍以其默认语言提供。”
我现在的问题是：
- 为什么我的配置中列出了这么多不可用的存储库？ 我目前有23个
Ign-entries，其中5个属于我的安装DVD。 - 它们会造成任何伤害（减慢更新过程，丢失列表，等等）？
- 如果这不是一个坏主意，我怎么能摆脱他们？
输出sudo apt-get update ：

为什么我的配置中列出了这么多不可用的存储库？ 我目前有23个Ign-entries，其中5个属于我的安装DVD。
缺少翻译不会使存储库不可用。 缺少InRelease文件可能，但如果服务器提供Release{,.gpg} InRelease Release{,.gpg}文件，则没关系。
它们会造成任何伤害（减慢更新过程，丢失列表，等等）？
略。 Apt对多个请求使用单个连接，因此某些请求会被延迟，但我认为这并没有多大区别。 只要正确的Release{,.gpg}也可用，存储库就可以正常工作。
如果这不是一个坏主意，我怎么能摆脱他们？
翻译： 如何删除apt中的翻译条目？
对于InRelease ，将不会有任何此类选项。 从2015年关闭的此function请求不会修复 ：
无论如何，4年后我们都接受了InRelease的新世界秩序，并且代码实际上发生了变化，这使得更难以避免至少首先尝试InRelease，因此关闭为wontfix。
