没有更新吗任何事物或者我的电脑出了问题？
最近，我的通知栏中出现了一个红色警告三角形：
当我进入更新管理器时，它告诉我 14 天内我没有更新我的包裹信息（我有）
如果我更新它，许多来源都停留在 0%，并且显示“空闲”而不是“已下载”
运行如下sudo apt-get update：
jack@jack-HP-Compaq-nc6400-EH522AV:~$ sudo apt-get update

我更新后还是提示我14天没更新包裹信息，这是怎么回事？
谢谢，杰克:)
在配备 Intel 集成显卡的 HPnc6400 上运行 Ubuntu 12.04 LTS。位于英国，因此我使用 GB Ubuntu 更新服务器。
答案1
我刚刚发现Launchpad Answers 上的这个问题。它帮助我解决了 Ubuntu 的问题。我希望它也能帮助其他人。
答案2
通常，添加丢失的密钥会更容易。
运行sudo apt-get update将出现一条错误消息，提示
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://repository.spotify.com stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 082CCEDF94558F59
错误信息以 结尾NO_PUBKEY 082CCEDF94558F59。您只需获取该数字并运行 即可sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 082CCEDF94558F59。
082CCEDF94558F59只需用apt-get update丢失的钥匙替换即可。
如果这不起作用，可能是防火墙阻止了你的更新，请检查Ubuntu apt-key 文档了解更多信息。
答案3
哇，我没有看到这些答案。
无论如何，最终，我删除了有问题的 ppa（Spotify 的 ppa），然后它又开始工作了。不过，我对这两个答案都投了赞成票。
