Ubuntu 新手。在其他软件源我有“Debian 4.0 eth”正式支持“non-us.debian.org/”等......“ppa.launcpad.net”并且安装应用程序已停止工作。
我想我是在安装 Blender 2.58 后第一次遇到这个问题
当使用更新管理器时，它会提示进行部分升级。
当尝试安装几乎任何软件时，我都会遇到相同的错误Package Dependencies Error或GPG PUB KEY丢失。
输出：sudo apt-get update && sudo apt-get upgrade

答案1
诊断
从您最近的编辑来看，错误很可能是由于您的存储库列表中的 debian 源造成的。
这可能会导致与标准 ubuntu 存储库发生各种冲突 - 我的第一反应是禁用这些非 ubuntu 存储库，而不是从 debian 网站下载公钥。
删除 debian repos 后重新运行。
sudo apt-get update && sudo apt-get upgrade
也许还值得添加以下内容的输出，以便我们可以确认您可能遇到的其他 repo 问题：
cat /etc/apt/sources.list
怎么修
我不确定您为什么添加了 Debian Etch 存储库 - 也许您可以将这个答案添加到您的问题中。
要注释掉这些存储库：
sudo nano /etc/apt/sources.list
找到以下行：
deb http:/ftp.us.debian.org/debian/ etch main contrib non-free
deb-src http:/ftp.us.debian.org/debian/ etch main contrib non-free
deb http:/http.us.debian.org/debian stable main contrib non-free
deb-src http:/http.us.debian.org/debian stable main contrib non-free
deb http:/non-us.debian.org/debian-non-US stable/non-US main contrib non-free
deb-src http:/non-us.debian.org/debian-non-US stable/non-US main contrib non-free
在它们前面添加一个“#”，使其看起来像：
#deb http:/ftp.us.debian.org/debian/ etch main contrib non-free
#deb-src http:/ftp.us.debian.org/debian/ etch main contrib non-free
#deb http:/http.us.debian.org/debian stable main contrib non-free
#deb-src http:/http.us.debian.org/debian stable main contrib non-free
#deb http:/non-us.debian.org/debian-non-US stable/non-US main contrib non-free
#deb-src http:/non-us.debian.org/debian-non-US stable/non-US main contrib non-free
写出文件（CTRL+ O）并退出编辑器（CTRL+ X）。
重新运行
sudo apt-get update && sudo apt-get upgrade
确认一切正常。
如何修复丢失的 GPG 密钥
对于每个十六进制字符串前缀sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys
例如：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 9BDB3D89CE49EC21
对每个丢失的 GPG 密钥重复上述步骤
如何修复代理后丢失的 GPG 密钥
如果您使用代理，上述说明将不起作用。幸运的是，webupd8 团队 (点击查看安装说明）有一个解决方案。你不一定需要安装 PPA - 你也可以从下载 natty deb这里并手动安装。
如何使用launchpad-getkeys代理请参见上面的 webupd8 链接。
如何在 Ubuntu 中安装 Blender 2.58
尽量坚持使用官方的 ubuntu 存储库 - 它将为您提供最稳定的系统。
在您的 ubuntu 中，您可以安装其他已在 Launchpad 上打包该软件的软件的较新版本 - 请参阅下面的相关问题。
其中一个存储库就是 blender 的开发人员的存储库 - 注意 - 我链接到此存储库的唯一原因是 Google 透露了一些链接到此特定存储库的博客网站。
sudo apt-add-repository ppa:cheleb/blender-svn/ubuntu
sudo apt-get update
sudo apt-get install blender
相关问题：
答案2
尝试这个
sudo dpkg --configure -a
答案3
我在使用 ubuntu 时也遇到了同样的问题。我只需要重新启动squid-deb-proxy，然后一切就恢复正常了。
